My Vehicles:
1999 Dodge Ram 1500 4x4 short bed standard cab 5 speed 5.2 (318) V8

I have a 01 Ram 1500 5.2L 5 speed and am going through a similar situation. When I regeared my rear end, I forgot to put the speed ring on the carrier like a bone head. Both the speedometer and odometer quit working. I drove the truck like this for about 6 months. When ever I came to a stop and pressed in the clutch, it would die. I guess Mopar engineers didn't want people just simply unplugging the rear speed sensor on the axle and driving and not putting any miles on the odometer. I had a rebuilt engine put in the truck during this time. The mechanic that installed the engine was dumbfounded when he took it on a test drive and it was dying at stops. Instead of calling me, he put in a new IACV and when it still was dying, he used his diagnostic tool to adjust the IACV setpoints. Truck still did it and he gave up. Within a month of getting the truck back I had the time to pull apart the rear end and put that speed sensing ring on the carrier. First test drive, code cleared, and no more dying at stop signs. Only problem now is on cold starts I get hissing out of the IACV hole on the throttle body and she runs rough. After a few minutes it settles out. I'm going to try a "throttle body relearn" to undo what he did and if that doesn't fix it, new O2 sensors. Those two seem to be common culprits
Interesting. I’ve got a whole video series on this truck, I’ve tried everything I can’t think of and it’s better but it still isn’t perfect. I’ll probably post a video soon of a compression test. I wonder if I’ve got a cylinder or two low on compression. Thanks for watching!
Notorious for leak at intake manifold plenum gasket. if you look down the throttle body and see oil, it's a good indication the manifold is leaking by. Hughes engines sells a kit, for around a $140 U.S.
I had redone the intake plenum with a Hughes engine kit about 6 months prior to when this video was put up. Didn’t help at all unfortunately! Haha
I have a 2000 dodge ram 1500 5.2... it did the same thing. Changed out all sensors on the thottle body with after market parts. The problem went away when I put on OE idle air control valve part (mopar).
If alot of miles, change injectors fairly easy ,Dodges are crazy.
Chasing the surge problem for two years, fuel pump went out ,changed it runs great 2002 59,000 miles wow.
This video was about a year ago, I have since changed the fuel pump, removed the cat, changed every sensor I could think of. Seems slightly better but still not right. Just living with it for now I finally gave up! Haha thanks for watching!
There is a better version of the second gen dodge ram magnum series engine injectors they have 4 holes instead of the normal factory 2 hole injector Chrysler used lol..
I just fixed a 98 5.9 with this same problem. O2 sensors they had good readings but the heater circuits didn’t work properly even though they had power and continuity.
Thanks for the suggestion! I’ll try replacing them
I love 2nd gens ... I have 2 left , I sold my 3500 dually and I have 2 left both 2500 12 valve diesels .. I bought a 1500 gas for the cab and I may try to sell the frame which is perfect still all the original paint on it ..
Gotta love 2nd gens. I’ve owned I don’t know how many…currently I only have one, my ‘99 5 speed isn’t going anywhere. I’m always buying/selling them though.
If rattles,PVC is fine. Mine was doing same thing ,check for right fuel pressure and O2 sensors
Yeah my guess would be the O2 sensors or the iac valve?!
Keep on looking for Shelbys. They're out there for sure. Little more info - They made "Shelby" Chargers with 2.2 Turbos in 1985, 1986 AND 1987. Additionally they had the actual GLHS in 1987. Story goes that Shelby bought the last 1000 Chargers for the 1987 model year and those became the numbered cars, the 1000 GLHS Chargers. I actually own both a 1987 GLHS and a 1987 Shelby Charger. Both have the 2.2 Turbo, but the GLHS has the "Turbo II" setup which wasn't introduced until the 1988 model year in the Daytona.
Interesting, I knew about the 1000 GLHS cars but I didn’t know they still made a normal Shelby in ‘87….I’ll be keeping an eye out, if you hear of one let me know! I’ll travel as far as I need to. Plus if I ended up in your area it would be cool to collaborate for a video or two!!
@@TheMoparGarage I'll keep my eyes open. If you get up this way, give me a shout.
I had 1994 dodge ram 1500 V8 5.2l. 2wd, i had same problem with rpm and i was told it was EGR need to be changed it out and i did that and it runs like a champ. So i went clean everything out make sure everything is doing ok.
So EGR is the problem!
Could be worth looking into! It’s been 2 years since this video was made and this thing still isn’t right.
did you check the IAT(Intake Air Temp sensor)? My 97 5.2 was idling rough in the mornings for about 30 seconds and the levels out and runs great for the rest of the day. Replaced everything like you did with no change. Changed the IAT sensor and it runs better in the morning. not perfect...but better.
This video was made a few years ago, I’ve done a lot of things since to try to get it to run right. Similar to yours, it’s still not 100% - but it is better than it was.
Fuel pressure regulator thats made to the fuel pump
Not sure if you got it fixed or not chased idling issues for months on my 99, would cam out per say and die randomly at idle all new sensors. If you havn't changed the belly pan gasket on plenumn its leaking and fouling no.8 plug. And for the idle fix, 2nd gens don't read bosch 02 sensors, needs to be ntk or denso upstream, and if you dont have a cat in it bosch downstream, and it'll never throw a cel. Verified on multiple trucks.
Throttle body mine did the same changed it and worked fine after the throttle body stayed a litte open looked closed all the way but It really wasnt closing all the way unbolted It and thats when i seen the problem sence It stayed a litte open It was running too rich
I have a 03 ram 1500 and it was swapped to the 59 and the RPM in Park rapids up to about two grand and then while I'm driving the RPM fluctuates and jumps up and down just a bit with out me hiting gas any harder
what did you do to fix it?
For my 1996 with 5.9 it was the throttle position sensor causing the truck to die after letting off the accelerator.
Thanks for watching! This video was from about a year ago, I’ve replaced or tested every sensor in the dang thing at this point. Removing the cat when I did an exhaust seemed to make a little difference. It’s only an intermittent issue now. Really weird one, only thing I can think is maybe a cylinder or two are a bit low on compression. For now I’m just living with it!
@@TheMoparGarage I needed to reset my throttle position sensor recently after an extended time with the negative battery cable removed. I turned the key to the on position without starting the engine, pressed the accelerator slowly all the way down and slowly let it up three times. Then I turned the key to the off position. I then started the engine and let it idle a few minutes. I shut it off and restarted again. I took it for a drive and all was good again.
I'm not saying it will fix yours, but it's easy and free to try.
@@roostercockburn690 it’s worth a shot! I’ll try it tomorrow and let you know if anything happens. Appreciate the suggestion!
I have a 1999 dodge ram 150o 5.9l. I have changed everything on the front in you, joints, upper and lower, etc. everything and I have a vibration that starts up around 30 miles an hour but it goes between 30 and 45 mph on a straight road. It starts to vibrate if you release the the gas pedal, it will go away. Can’t figure out what it is please help.
The first place I would think to check is the driveshaft universals. Have they been changed yet?
Been dealing with an intermittent issue where my 99 5.2 won't idle. Only happens on startup though for maybe 30 seconds or a minute. Was hoping to see the fix here, I'll have to dig through what you've done so far and see if I get lucky.
I've got a whole Playlist on this truck if you want to follow, it's been very hard to track down. I've done a fuel pump and almost every sensor in the truck and it does seem to be better than it was, but still not quite right.
@@TheMoparGarage I watched those other videos a bit earlier today too, hoping you came up with the solution. Bummer that wasn't 100% the case. I'll have to deal with mine too if it gets too much worse.
@@mulletsquirrel the new fuel pump made the biggest positive difference. It only seems to do it once in a while now. Just a very weird issue with no obvious solution. Only thing I can think is a cylinder or two a bit low on compression or something internal like that, because I’ve tried everything else. It’s not too bad now so I guess I’m just gonna run it! Haha.
My 318 magnum V8 doesn't even have the lifter ticking issue either lol.. could be the injectors ticking alot of the rams have anyways mine doesn't do that..
Iac valve maybe?!
I would have bet it was a vacuum problem too. I think what it needs is a rip through the mud. Redline all the way
Worth a shot, clean the carbon out of ‘er!!!
Hey bro it's me TurboCarlos, I was going to ask where did you get your turbo lines when you bought them because I'm over here in California and I went to the local auto parts store and they do not have them where did you get yours at?
Turbosunleashed.com. They have a kit for both the Garett and Mitsubishi turbo setup
Did you try the map sensor?
I tried every sensor in the thing! Haha…there’s a whole series on this truck, I got it running a lot better, but still not 100%.
Mine keeps killing o2 sensors any tips on where to look I inherited it and want to fix it up and keep it. it’s a 1998 2wd 5.2
Are you having trouble with the pre cat or post cat o2 sensor?
Pre cat
@@gabeedwards8221 all of the V8 magnums, 5.2 or 5.9, are known for the intake plenum gaskets going bad. This causes oil to get up into the intake from the valley of the engine. The truck will start to burn oil pretty bad which will plug up the o2 sensor. If I had to bet, that’s likely the issue. Hughes engines makes an awesome kit to re-do the plenum gasket with a nice aluminum plenum plate, which takes the place of the thin steel plate that comes stock. I installed the kit on this truck and a few others I’ve had, it’s probably about a 3-4 hour job. There’s a really nice series on UA-cam about how to do it.
Thanks man I appreciate the help I’ll let ya know what I find
@@gabeedwards8221 always happy to try to help, good luck!
Idle air control valve?
Great thought. I’ve actually got a video that will be coming out Tuesday where I investigate that possibility!
Relearn throttle position sensor
I think I had tried it already at this point…there’s a whole series of videos on this truck I’ve gotten it to run almost 100%. Maybe not quite but close.
@@TheMoparGarage I’ve got an’04 with similar gremlins
@@DanielJohnson-ec8rk sometimes no matter how much chasing you do there just doesn’t seem to be a way to ever get them quite right.
It sounds like a bad ground. Maybe check that out before replacing every part under the hood 😂
Hahahaha....you know what the worst part is? After 3 days it was back misfiring again. Must have just been a computer reset that temporarily fixed it? No idea, back to square one.
Jus change your I a c valve..
This truck has a series of videos on it trying to get it running right, I changed the IAC in one of them. Still no luck!
