When I had the MAF off one of the things I noticed was that there was a small amount of oil in the plastic hose ( the baffled one between MAF and Throttle body ) how clean/dry is this meant to be ? When i had my HG done i asked for the breathers to be cleaned out aswell, new throttle body gasket etc.. this is only a few weeks back.  :-?

[Iain]

Erzy,mine is the same,a slight covering

Right, ran it normally then unplugged MAF and ran it again,no noticeable change to anything

 

[Erzy]

Right nice one, so we thinks no probs with our MAF sensors ?  So problem could be gunked-up breathers, anyone know how clean/dry these large bore pipes should be ? Like i say garage cleaned breathers comp. only few weeks back.

[Iain]

I dont know anymore mate,but its p*ssing me off big time

I'm actually seriously considering getting rid of the car

[Erzy]

I know what you mean Iain. Sick of everyone staring at it like its a tank when i first start it. So frustrating, thought there would be an obvious fix. Looks like i'm stuck with it though - no money after new Cyl.head, new HG etc... Lets hope someone can help us poor ( non V6 ) owners

Listen lads, & take everything I say with a pinch of salt as i'm a bit pissed as I write this! I have experienced everything you are now going through and can only speak as I found? The first 'Port of Call' is the Cam Sensor! Easy fix & not too expensive, especially if you can get one second hand from a 'breaker' on here! The next 'Port of call' is the dreaded Crank Sensor! Again. cheapest fix is a guy with one for sale on here, but an absolute PITA to replace! Both these sensors account for the majority of fault codes & uneven running on the 2.0 + 2.2 Omega! Good Luck in your endeavours to solve your problems!
& apolologies for any alcohol induiced smelling mistakes! 

[Erzy]

Cheers philrich, a proud Englishman. So either of these two sensors can be on their way out and there won't be any codes stored/eml lights? Oh and also my good friend, are the plastic breather tubes after the air filter supposed to be bone dry?

[Erzy]

Anyone else help us 2.2 owners

[mathewst]

Hmm air/fuel mixture problems possibly.
Can any one of you guys get real time data and maybe try to compare it with each other or mine if needed?

[Kumamoto]

Gosh...i  have been having the same problem for the last 3 months or so. It actually started after the miggy consumed some dodgy fuel. I had the tank cleaned and petrol filter replaced. But it did not make any difference.
I listened to advice here and changed MAF sensor ..again  no difference.
I changed the CRANK SENSOR with a brand new GM one again no difference.
I have also changed the CAM SENSOR with a brand new GM one....still did not make a difference.

I took to the local dealers here with TECH II......no fault codes. The car was there for 5 days and they fiddled with everything including injector nozzles, still no joy.

I  replaced the  engine temprature sensor and switch  2 days ago still no joy.

I now have a mechanic who is suggesting i get IRIDIUM spark plus becuase the ones i have do not seem to spark properly!! I have ordered them from ebay an will advice once fitted.

Oh did i mention that i also changed the coil back and fitted a brand new bosch one??

At least on the brighter side my car only plays up in the morning for about 30 seconds and you have to turn the key  a few times. After it warms up it runs perfect the whole day!!!!

It would be great if we could find a solution to this problem affecting the 2.2's

From my experience  with these problem i would suggested you go about changing parts especially if you have to buy them. Luckily for me as i am at the other end of the world i had stocked up on the parts that are mostly likely to fail (Cam,crank,maf,coil pack etc)

[mathewst]

Did any o you guys tried to use injector cleaners and engine cleaners. I also had my engine partially rebuilt but had no problems like this. (although I use cleaners regulary and give a mig a blast on open roads relatively often)

[Iain]

i'm sick of mine! its really getting on my t*ts now 

[Auto Addict]

Just a thought, feel under the scuttle, is it damp?

Could be water getting onto the coil pack connector at the back of the engine.

If it is damp, then the bottom rubber windscreen seal needs re-seating and sealing.

Hello Guys

I went through this a few weeks ago, fitted new plugs,changed coil pack no better, unplugged maf sensor no change, fitted rear exhaust still  no better but noisier than the one the idiots at the exhaust place knocked a hole in.
Then after trawling the forum I decided to risk a dealer MAF sensor 114 squids. Immediate cure, seemingly the ebay ones are not always worth the hassel.
Its a pity I dont live near you guys it would be easy to swap the new one to establish if it was the maf or not.
Good luck happy hunting I was also ready to get rid of the car.

[Erzy]

Iain and ronnic, any joy yet lads ? So are the large bore plastic pipes either side of the maf supposed to be bone dry?? , like I said garage did breathers few weeks back so how comes there is oil in there.Do I need to clean breathers again along with butterfly valve and gasket etc.... :-/
