- Vauxhall Opel Astra G Mk4 1.8 Irmscher Throttle Body Cleaning. This Vauxhall Astra has a lumpy tick over so I decided to clean the throttle body. I found a blocked inlet so hopefully this will cure the problem.

i know this video is 2 years old but it may help someone. If you find your z18xe 1.8l running poorly/ hunting idle, and it almost sounds like the engine is misfiring on a cold start, then smoothen out. Its most likely the Fuel Evap valve is stuck and needs to replaced or the valve's hose is cracked, causing a vacuum leak. This can also throw sensor codes like MAF and oxygen sensors, when in reality is just the fuel valve that comes off the throttle body. Good luck and check your coolant lines
hello mate great videos wifes got the same car, been to moon and back been such a reliable car , just recent and dangerous to drive the car accelerates by itself only when moving revs fine when parked any ideas faulty ecu ???
Love that your back on cars Martin. Im not a bike guy so was drifting away.
Just followed your instructions and my 21 year old Zafira is running smoothly again. Exactly the same problem with that tiny hole blocked. Thank you.
Well done.
picked up the same car recently,same 1.8 engine,took the throttle body off after first watching this video and the body was filthy and the small hole was also blocked,took a good while to get it cleaned using stiff wire and plenty of carb cleaner but finally got there! ive watched all your videos on this car and the way you explain things step by step and the camera views really helps,i now plan to do the timing belt in the bear future now i know how its done! great videos,thanks
That's great Alec, Glad the vids have helped bud.
what a great good video, very clearly explained and filmed!
I have the same problem and will try it tomorrow.
my thanks are great.
greetings from the Netherlands.
I’m really enjoying this Astra series. Thanks Martin. 👍🏼
Glad you enjoy it!
Be honest now Martin, was that a fart slipping out at 3:30 😂🤣
No, that was Sharon's brother making silly noises.
Very useful video. Experiencing hunting running on my 1.6, guess the thottle bodies are similar, I'll be giving it a go in the morning. Big thank you.
Perfectly explained, great video going to do this to my 1.6 meriva.
Good spot there Martin, very easy to miss that. Loving this series, keep em coming 👍
Thanks 👍
Thanks for the Astra episodes Martin! 😜
I guess I'm kind of off topic but do anyone know of a good site to stream newly released movies online ?
@Paxton Zayd Flixportal :)
@Weston Genesis Thank you, signed up and it seems like they got a lot of movies there =) Appreciate it!!
@Paxton Zayd no problem =)
Loving the videos Martin, your step by step hands on approach is better than any Haynes manual. Thankyou
Thanks 👍
Beautiful work boss..it can't get any more easier than how you have explained it..
Thanks 👍
Well done Martin, that really needed a good clean.....take care
Thank you Martin I love watching your videos I am from South Africa
Great video, nice to see the job being done properly 👍
Thanks 👍
Legend mate, you helped me fix my car after the mechanics gave up.
Nice one Michael, Well done bud.
Hi martin, thanks very much for your astra videos. I'm working on a zafira A 03 and I have had the same idling issues. So I've found this very useful thanks 😊 👍
The video after the next one is worth watching on the final running issue.
Čo robiť keď otáčky kolišu škrtiaca klapka môže byť ani ťah nemá dobrý
Good video, well done , nice and clear instructions. ,I had a vauxhall once ,rough idle , turned out to be a 1/2 block cat, it just started to fall to bits internally , that was a strange one...
Nice job, The maf should give fluctuating readings on idle
Top job and well worth doing. Looking forward to the next one.
Glad you enjoyed it
Top work as always Martin .
I still think it would loom better without the body kit ( tacky)
Top job as always
Thank you! Cheers!
top hose off..dump a can of carb cleaner in..job done...:) just remember to fix top hose back on..or car won't start
Good on you Martin another informative video on car issues and t heir repair 👍👍👍👍
Another great job Martin good to see you remembered your gloves this time lol 👍👍👍👍
Absolutely lol
Nice work Martin I had a blocked rocker cover breather pipe, that was the problem with my ventra years ago same engine as yours it was totally blocked in the rocker cover itself
Thanks Phil
Martin
Tinkering time is best time really enjoy watching these videos more please
Phil in stoke

Ye mine was bad compared to this great video I had a blockage in that pipe aswell I used a metal wisk I cut the ends of to poke in
hello mate great videos wifes got the same car, been to moon and back been such a reliable car , just recent and dangerous to drive the car accelerates by itself only when moving revs fine when parked any ideas faulty ecu ???
Now with most of these model engines the throttle body is gummed up. Can you explain what stops the oil coming from the engine as they don’t seem to have a pcv valve or how to set up a catch can to reduce the oil and stop it from blocking up the hoses. Or is there maintenance to be done inside the rocker cover to ensure the oil doesn’t leave the engine. Thanks.
Fantastic work buddy 👍🏻
Thanks John👍
Them two pipes in throttle body ,one goes to water pump one goes to expansion bottle only for one purpose, to bring hot water to throttle body and warm it up in cold weather ..
How many times have you taken off that to cover 😜😜😜

@@retrorestore I thought this was the 3rd? Belts, plugs and now air flow?
@@mercedes_and_more oh yes, its 3 lol
If the idle is hunting try the idle air control valve...
Certainly know your stuff Martin, I reckon the time you check the rest it will be running as sweet as a nut! You vids are great to watch! 👍
Thanks Dave.👍
Good video, looking forward to the next one.
Cheers mate, great help, poxy car playing up on Xmas day. Of course it does.
No problem 👍
Sounds alright to me. Sounds healthier.
Not sure if your cards link is working mate, each time you mentioned it and pointed, nothing was showing.
Great video mate 👍
you will be surprised what problems a dirty throttle body will do, was the fuel filter even doing anything, with it been fitted the wrong way, who knows.
shout out Sunday lol good vid keep in comeing
omg that sounds really nice better then what it was mate
Hahahaha did you fart at 3:30 xD
No, that was someone making a silly noise
@@retrorestore hahaha😂
It was pretty gummed up in there,I have a vectra with a z18xer engine which is different but i think they share the same
problems with the thermostat housing which is electrically heated and they seize open,a sure way to tell is the temp gauge
drops to 0 when on a long drive but around town can't tell and heater goes cold.Yeah suck eggs i know but sometimes this can be missed and with affect engine performance and fuel economy.
Very noticeable in the winter but summer you can hardly tell.
Just a thought.
Yes they all suffer with the thermostat being stuck open. Both the Vectra ans Astra both have this issue. Its a £55.00 thermostat as well .
Nice job very helpful
I seem to remember that when cleaning it is important not to open the butterfly valve. Might be worth mentioning, as I note you didn't open it. Just as a heads up for others.
I did open it bud off camera.
@@retrorestore good to know, thank you
What a great video? Got a maf sensor problem, and after replacing it the problem persists. Someone advised me to have a look at cleaning throttle body. Does anyone have other recommendations?
when you having the same cold start problem and waiting to see if you find it ??? come on martin bring out the next video
2 video's time bud.
Great Vid Martin 👍
Thanks 👍
Another spot on video 👌👍
Thanks 👍
I wonder how much that job would have cost at the garage or dealers Martin.
Any job at a garage is dear Dave lol
I cleared throttle body on my 1.8 Astra,than i got lean exhaust and throttle body failure,i cleaned it with brake cleaner
Nice job mate.👍
Thanks 👍
Good vlog martin
👍 nice one Martin 👍👍👍
Thanks 👍
well played sir
Was that Chris with the cameo role? 😂
Finding that blocked hole should improve the running,
Haha, yes it was Jason, I couldn't cut that bit out but he done loads more noises lol
Another good job and vid nice 👌 👍
Thanks 👍
Top video. Did you check that the hose leading to the blocked port on the throttle body? I had an Astra F that had a full vacuum pipe totally clogged
Yes I did
Where is the face pulling parrot man . Good job.
Haha, The wind changed and he got stuck like that Pete lol
@@retrorestore That will teach him lol.
Great video, Thanks Martin. Will be cleaning my throttle on the weekend. Hope no rain . :)
The throttle body was gunked up. It will be the EGR that's caused it.
As far as I am aware this engine does not have an EGR valve. It does have an intake manifold air control solenoid that is often the cause of a lean mixture.
No Michael. not in this case.
Martin I have a short term fuel trim of 15.6% and a long term fuel trim of 8.6%. Have you had any problems like this on your vauxhall? These figures are at idle so I am going to rev the engine tomorrow to see if the short term fuel trim falls, if it does I think I have a vacuum leak.
We have no issues with this car bud so I can't tell.
@@retrorestore Cheers Martin.
nice martin
Hey man love your videos! I have an borth american Astra H with the 1.8 engine (Z18XER) and it has a P0068 check engin which is mass airflow colleration. Would cleaning my MAF get rid of this code?
Its best to just change it but you could give it a try.
Enjoy you videos. The yellow label, what is Power Sound. Thank you.
Don't know what you mean bud, sorry.
@@retrorestore the label just above engine bulkhead on the Astra just curious to its meaning.
@@richardprice4362 I think its something to do with the alarm system.
Nice methodical approach.... keep up the good work 👍
The bit he cleaned 😂
@@shanekneeshaw3483 ... no, the whole series 🥴
Thank you! Cheers!
What is a throttle body Martin🤞
might do mine now. what was the pipe that connected to the hole that was blocked for? is that the crankcase breather?
Yes it was the smaller of the two
Hello!
I would really appreciate your help if possible
I ve been struggling with some jerky acceleration and deceleration for some years now
I think a few years ago a mechanic sprayed some cleaner in my throttle body and it was working nicely
I was driving a lot at that time (20.000 miles per year so after a while I had it again)
I cleaned myself many times but it always looks clean and I never have any error codes but still runs jerky
What could it be?
Could be a coil pack, You need to get an OBD11 tester plugged in to see if there are any codes.
@@retrorestore hey thanks for the reply
I have an obd tester
There are no codes but I ll recheck
I checked the coil pack today
I changed it 3 years ago and still looks good
I managed to take my throttle body out and took the vacuum hose off to see if the two sides communicate (where the small hole is)
And yes they do
I also have a new egr and a new lambda o2 sensor
Cheers mate. Really clear.
I'm no genius but that could
Be the problem....
Put a fuel additive in there
The one that was blocked was that the oil breather ??
One of them, yes
Hi Martin, What did you clean the hole with inside the throttle body? Mine is clogged up bad!
I showed that in the video bud. welding tip files and carb spray
@@retrorestore cheers Martin, I'll get myself a set and give it another go.
Common fault on all Vauxhall’s crankcase breather blocking even in carburetor days
Martin are you having log sheds like the one already up or metal ?
No, we'll build our own. These ones were pre made.
Can this issue cause the spanner light to come on? Cheers
Best to plug a diagnostic scanner in to see what codes have come up bud. It could affect other sensors trying to compensate to the body being out of range.
was that a trouser cough at 3:27 lol
No it was Sharon's brother making silly noises.
A little bit of this... a little bit of that...
Waste of time cleaning the maf just get a new one martin
All in good time Daz
