- In this video I tackle the rough idle and off throttle misfire on my 1985 Volvo 245, it has a stock b230f and LH2.2 electronic fuel injection but no obd of any kind. But with less than $10 of tools and 10 minutes I'll show you how I attempt to find the problem
My IG: / 240rescue
Met so many boastful people when I've been travelling, and then I see people like you, seem so genuine and not pretending like you know everything. Never had the urge to go to the US but people like you make me think that there are so many cool people I'm missing out on! Random rant but loved your video!
Wow thanks a lot that’s very kind
I can confirm. Chris is great! 👍
I've had a 240 not running for 4 months, five different mechanics and I have come to rule it down to the fuel injectors but now every shop I go to to ask them to change them out to a remanufactured set is acting dogmatic saying that they never go bad but there were three quarts of gas in my oil just from trying to start it between tests and different mechanics and we changed the fuel pressure regulator and three of the sparkplugs are still fouled and I'm ao frustrated nobody will look at my car for me because "it's too old" or "fuel injectors never go bad". Ugh. In need of a mechanic in the Rhode Island USA area pleeeeaaaaase lol
Hi buddy ,got the same thing with my 240 turbo ,intermittent crazy jumping idle and cylinder 3 is 65'c while others are 200'c!!!where would you start with that?runs nice when driving but stalls sometimes when stopping!!??I'll drop you a treat off in your PayPal for any answers cheers buddy
I would do a compression test first and if that’s all clear I would probably try the intake mani gasket first!
What a fantastic video! Thanks for sharing, I'll definitely be using this method on my 91 wagon. Do you happen to have Amazon links for the spark reader and light? Or did you pick them up at an auto shop? Thanks!
Thanks man, I don’t have any links but they definitely are online, my tools were inherited but I did a quick Google for a price check, I just haven’t tried the ones online so I can’t give any recommendations
My 1988 245 IS APROACHING 700 k MILES ,STILL ON THE ORIGINAL REGULATOR, ONLY THINGS I HAVE DONE TO MINE IS ALTERNATOR BRUSHES, TIE ROD END ,STILL RUNNING ON ORIGINAL SHOCKS, I HAVE REPLACED BELTS, INCLUDING RECENT TIMING BELT, WATER PUMP ONCE, FEW OEM BRAKE JOBS,AND TIRE CHANGES ,AND ALWAYS 5,000 MILE CASTROL 10-30 MY ENGINE LOOKS LIKE NEW INSIDE AND NEVER BURNS A DROP OF OIL ,ENGINE LOOK NEW INSIDE VALVE COVER ,THAT THE CASTROL DIET. I THONK I DID CLEAN THE PVC / FLAME TRAP TWICE ,TRANSMISSION FLUSH ONCE, A U JOINT, A COUPLE WINDSHIELDS,AND ONCE A HATCH STRUT REPLACEMENT, BLOWER MOTER GROWS BIT STILL WORKS, HAD TO FIX WIPER MOTOR BACK IN 2001 , OTHER THAN THAT, I WOULD DRIVE THE CAR TO ALASKA TODAY, AND STILL KNOW I WILL MAKE IT THERE AND BACK,I LIVE IN MISSOURI. HOPE TO RUN THIS ONE OVER A MILL, ALSO MOGHT MENTION THE CAR WILL NEVER USA A DROP OF OIL, BEST CARS EVER PUT ON THE PLANET.
VOLVO FOR LIFE HAS PROVEN ITSELF TO ME
So true
It would have been interesting to pull the spark plugs for all 4 cylinders and compare them. There are several resources on the Internet that show the spark plug comparisons between and engine that is running rich, lean or properly.
Good point, I did have all 4 plugs out while doing the initial compression test, but they all looked pretty similar and a healthy color, I think because the misfire was so intermittent and such a new issue, it wasn’t enough to foul the plugs in an obvious way
Definitely appreciate the content you shared in the video. This will come in handy for sure. You make it look almost too easy; but, know I have been frustrated before with these types of problems. I also like how you try to explain the reason behind what you are doing. Keep up the good work!
Thank you so much, comments like this really make me appreciate the community
Hi from the UK buddy! You seem to know your way round a 245!i have a 2.3 auto Estate that stalls when coming off idle when I have accelorated hard and idle is rough as a bears arse! Lambda light on and code 133 on led code reader??? Any help gratefully recieved, cheers 👍
133 is a throttle switch for lh2.4, I would start with that
Nice Virgo tshirt. Wish they would have come in 17" !
I love your videos! I just posted a video of my daily driver after getting a new alternator. Id love to hear your thoughts on my 82 240. I've had her 12 years and feel privileged to keep K-Jet alive.
Thanks for the compliments. I just watched your video of the warm start, it honestly doesn’t seem that bad to me, but if all the fuel stuff has been untouched I would suspect the accumulator, pop the hose off the back vent and see if it’s leaking
This was an excellent video. Thank you for the sage wisdom. These cars really are an obsession.
Thanks a lot, and yes they sure are
Very helpful video! I also use the spray bottle to check for vacuum leaks.
Yes, me too! Its a very versatile tool haha
This is great! Are you still doing those Africa door chimes?
Great video man! A lot of great info for the community.
Thanks a lot I appreciate that
@@240rescue absolutely you've got great content and its nice to see your channel growing.
Mine runs great. Once in a while it stalls at a light or when I'm driving. Never know when.
I thought it was a faulty fuel pump since it's original since 92. Replace both fuel pumps. Great for a few days then stalled at a light. Wait a minute and it fires up with no issues.
Checked the codes. 1-1-1 no faults.
Anyways wonder if you have any idea.
92 240 wagon.
When you replaced the tank pump did you make sure to use a proper rubber transfer tube?
Awesome video! Need your expertise on my daily 92 240 , it cranks but is not able to start the engine. Checked battery, sparks, injector, all good.
Any ideas? Thanks!
You need to make sure timing and compression is good, and then check fuel volume/pressure
I have a question if I may. I've just put our B230FK 940 back on the road after a 10 year hiatus and a cracked cylinder head. We installed a replacement and although the car seems to be running well and giving good power, when it idles there is a slight dip off rpm every fourth beat, if you get me. e.g. say it's idling at 750, it will sharply dip to 700 for a split second and then okay again. Anything like that sound familiar? A new NGK coil was installed (not by me) when getting it going again with Bosch leads, so I'm at least going to get the Bougicord leads and a proper coil and start from there. I've just been slowly working around the car fixing broken stuff so haven't investigated this properly.. yet. Very useful video!
I’m not familiar with the fk but I had a similar issue with a b230f with LH2.4, eventually the ecu just needed to adjust after not being run, hope you figure it out
Great video Chris! Thanks for a bunch of useful tips! Need to get me some diagnose lights and sprayer bottle😀.
Thanks I appreciate it, gotta fix these bricks on the cheap
I have a rough idle on my 82 kjet. I recently replaced all PCV system parts with new ones. Cleaned out the in take manifold and the kjet body. I started the car after assembling and torquing everything, I noticed it has a rough idle, since I have mechanical injectors, could it be possible that these may be failing? All vacuum lines are good, many i just replaced to new ones. Anything could help.
I’ve just released a new kjet video
Very nice video! Can you tell med where you got that t-shirt from though?! I love it!!
I made it! I’ll start selling them again soon
How do I diagnose a 81 Let, if both fuel pumps work, and the filter is good and it has new injectors but has a rough hesitation when started and running?
Kjet is trickier, but it’s all reliant on fuel pressure
I really appreciate the misting bottle trick
Thank you, just be safe when testing
If your fuel pressure regulator was leaking fuel across the diaphragm that would make the first two cylinders run Rich and misfire thus running cool. As far as the injectors go I would like to see how you clean and test flow volume. Good video.😊
Thank you, you can definitely clean the injectors at home on the bench, volume test too but you would have to build a rig for it
Great Video! Thanks for sharing. The 240DL is a great vehicle, sedan or wagon. Would not mind finding and buying one again.
Thanks for watching, there’s no better time than now to buy one!
Thank you for the very well done and useful video.
Please consider turning down the the thump thump sub-woofer destroying music. It is way louder than the actual content so one has to ride the gain all the time.
Thanks for the feedback I’ll try to keep the music low
are you chris NG? Ive been looking for a custom door chime for my 240 for 5 years now, ever since that kickstarter, whatever happened to that?
Yes it’s me. I completed the KS and sent them all out, but there were a few that never shared their address
@@240rescue would I be able to order one from you, if your still able to do it? Just a one time thing, I was never able to fund the Kickstart at that time but I would gladly buy one from you if you are still willing to make one
Great video!!!! Volvos are simple cars if you know what your doing
That’s true, they really are simple machines
Good eveing :D o you fix a lot of volvos and sell them? and are you in California?
I do occasionally sell them, I am
In TX
Don't forget& if car is running rough check the PCV for clogged crap in the flame trap& vacuum hose.
True, the pcv system is important to keep clean
What's the PCV ? Just getting a k reg Torslanda going after long term storage. Cheers
If the injectors are that cruddy, wonder how tired the fuel filter is?
Where you get your parts for these ol' gems? Local PEP boys kind of places?
It’s always best practice to replace stuff from the tank forward, both the tank screen and under car filter had been replaced recently, so the last thing was the injectors, parts can be found on ipd or fcp, or even rockauto!
Cool.
The 240's were my favorites to work on at the dealer I worked at in the mid 80's as a Volvo Master Tech. Definitely NOT fond of the diesel versions!!@@240rescue
Great Video and honest simple
advice keep up the great work
Thank you!
Oh to have fuel injection - I have k-jet ;)
I have a slightly lumpy idle
Kjet is a little trickier
@@240rescue tell me about it ha ;)
Looking to buy a 245 wagon or a 242 sedan. Do you come across any for sale?? Thanks in advance.
Don’t see any right now but I’ll keep looking
What part of the country are you located? I have one of the cleanest 240's you will ever find.
Thanks on this, I’ll check mine. I took my 240 DL in for tires after driving -150 miles just fine. Volvo check my car over as a curtesy and when they gave the car back it was missing at low rpm and sluggish until high rpm’s. I put two bottles of heet into the tank running the tank down hoping if I had some gas water it would move out. Plugs, router, distributor cap and wires are new. I had no problems until I picked up my car . Volvo put on a new air intake tube for 300$ and no positive benefit in performance.
Good luck, hope you sort it out
Howdy Chris, great to see you again!
Hi Brock!
I noticed you replaced your master cylinder. What were your failure symptoms and how horrible was bleeding the system? Or did you back bleed.
Failure symptoms usually include loss of fluid, sinking pedal, and/or brake fail light. Bleeding isn’t hard with a power bleeder, but there is a specific pattern you have to follow and old rusted bleeders can snap. I usually hear cycle and soak the bleed nipples for a few days beforehand. I also do at least 2 full bleeds of the system, usually 3
Just seeing if anyone would know, 1990 Volvo 240 not getting spark any reason possible why?. (saw one on Marketplace just seeing before I look for more issue why no spark)
Sorry for the late response but lack of spark could be from a faulty crank position sender or a burnt out ignition amplifier
Hi I’ve seen that u have a video on k-jet. There isn’t much content about them on yt, but could u do a video on what it take to swap k-jet to lh2.2/2.4? It would be greatly appreciated!
I’m on it!
That T-shirt is legit.....
Thanks, they’re original designs printed by me
While checking the misfire, did you also check the engine mounts, they sometimes if they are cracked or broken, the engine shakes terribly
Good tip, I did check the mounts and they are in decent condition, I replaced them with diesel mounts not long ago
Where did you buy the regulator from?
I bought mine from rockauto if I recall
@@240rescue thanks! I recently bought an 89 240 and it ended up being the computer was the issue got her running now!
Great video 👍
Thank you
Hey I have a 240 and it cranks but no start this happened after I removed trailer wiring , while doing that I shorted a wire out because I did not remove the battery out of laziness… any ideal what it could be? Sometimes it starts and then dies right away as soon as I stop cranking
You may have blown the fuel fuse, either 4 or 5 depending on year
@@240rescue thank you I will give that a try
great vid!
have a '91 240 DL - first began stalling out exactly 5 years ago today. pulling my hair out here.
replaced so much to no avail. cps. entire intake restored, oil pump + PCV system entirely new (ridic difficult since I did not remove the front axle to do it), both fuel pumps new (in-tank pump replaced twice just because), new fuel filter, new gas tank with line-x exterior custom-meticulous, new OEM plugs, distributor cap + rotor, new bosch coil, new plug + wires, new air filter, cleaned MAF several times now, new starter, new optima yellow top, cleaned all grounds, 100% fully restored original alternator (by hand), new OEM diesel motor mounts, new engine coolant sensor, cleaned ignition valve, new water pump, new timing, new belts, replaced all inboard fuses, new fuel pump relay, new fuel regulator...
all my me by hand and more that i simply cannot recall right now - it's STILL STALLING AND HAS A ROUGH IDLE!!!!! god save me. last time i drove it before it stopped starting up (recently)...i noticed that the left (driver's side) headlight beam was very low, but it wasn't like the bulb had fully burned out - seemed really strange. the right headlight bulb was fine, but the other acted like the alternator was dead - which I'm telling you is not the case at all. if the alternator was dead or acting up, then the entire system would behave like that left headlight.
so question to you: i'm getting a 2-3-4 code on port 6 of OBD check. that's technically a throttle sensor issue. this is a brand new code read. wasn't there before now. i know. nuts. anyway...could the throttle sensor cause engine stalling and also no starts and, to your video's point, could clogged injectors cause the sloooooow stalling that this car typically has - especially when the weather is hot outside? my car doesn't "die" like i turned it off with the key - you're driving along and then you feel this drop in the engine power for a split second....and you think you imagined it but you didn't imagine it - it was very real........and then everything's fine for maybe like 5 seconds.....and then.......yes....it slowly starts dying like you are turning off a water faucet slowly, like you're running out of gas....and then all the dash lights come on and you for sure best not still be in a lane on the highway - you best have gotten off the road during that 5 seconds it gave you as warning. really scary stuff when you're in it and you have kids and other people are flying around you and they have no idea your car is dying.
huge thanks for any info!
EDIT: I just sprayed water on all 4 exhaust ports and water evaporated on contact on all 4. appears that none of the cylinders are firing colder than what is normal.
Keep me updated on this, Just bought someone else's project 92' 244 and am having stalling issues at stoplights and low speeds.
In LH2.4 cars, I assume it’s 2.4 since you said 91, some Ecus can be at fault, particularly pink label ones, but also check injectors and pressure. As far as the TPS, I can’t say if it’ll cause a stall, I’ve not seen that before
@@cameronjkramer Hello there. To be honest, I have not had the time or mental stamina since my initial comment above to dive back into the problem. Been fighting this fight since Dec 2018 and by last summer I had run out of patience. But I will for sure write back if and when I find the source of the problem.
@@240rescue Hello. Yes, the 2.4 is correct. I have read about the ECU as well and will check into this asap. Have not specifically checked the injectors or obtained an accurate fuel pressure reading. Will look into what it takes to perform this. Appreciate any other thoughts you may have on this front Thank you!
My 940 is having the same issue
Good time to check some of the fuel components
@@240rescue yep gonna check the fuel regulator and fuel injectors
Thanx.
You’re welcome
What state are you in bro?
I’m located in Texas
@@240rescue me too i have 240s(DFW)
Brother, I *need* to know where I can get that shirt you're rocking.
Great diagnosis tutorial, a lot of good advice here. Thanks
Thanks, I design and print the shirts myself, I’m not printing any more at the moment, but feel free to dm me your shirt size on Instagram and I can see what I have left
@@240rescue Aw man, dope design. I'm in Europe though, so shipping might be a show stopper I'm guessing :/
