Vauxhall Opel Astra G Mk4 1.8 Throttle Body Cleaning

[@tye595]

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 ???

[@SuperGarfitz]

Love that your back on cars Martin. Im not a bike guy so was drifting away.

[@rippenburn]

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.

[@retrorestore]

Well done.

[@Juke-man79]

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.

[@alecg4820]

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

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 😊 👍

[@jonathanhammond3748]

Thanks again Martin, another great watch!

[@whiskey3930]

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.

[@tedvegas5586]

Top work as always Martin . I still think it would loom better without the body kit ( tacky)

[@williammcgowan6687]

omg that sounds really nice better then what it was mate

[@arts6535]

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 ..

[@normsmowers4758]

Another spot on video 👌👍

[@retrorestore]

Thanks 👍

[@blarkdexture8899]

How would the a small clogged hole affect the engine?

[@steves427]

Basically it's an air vent. The throttle body equivalent of a bunged up nose with the same effect. If one of them is blocked, it could affect fuel, air or fuel/air mixture volume delivery within the throttle body & onwards to the engine & a likely cause for any / the rough running in this case.

[@MARKLOCKWOOD2012]

Sounds alright to me. Sounds healthier.

[@gernkmccory3836]

Cheers mate, great help, poxy car playing up on Xmas day. Of course it does.

[@retrorestore]

No problem 👍

[@SJHughes]

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.

[@retrorestore]

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 .

[@jayf3qt]

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

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.

[@adammcallister2260]

[@retrorestore]

Yes I did

[@TheSvecias]

Great video, Thanks Martin. Will be cleaning my throttle on the weekend. Hope no rain . :)

[@sorinionica9519]

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?

[@retrorestore]

Could be a coil pack, You need to get an OBD11 tester plugged in to see if there are any codes.

[@sorinionica9519]

@@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

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.

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.

The throttle body was gunked up. It will be the EGR that's caused it.

[@elliottpeters2996]

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.
