Hi everyone, I am new on here...
I have recently bought an 02 Astra SRI turbo that seems to have a running issue. When I bought the car the mil light and the traction control light was on the vehicle was showing a fault with the maf sensor but drove fine with it unplugged. I have now replaced the maf sensor with an item from german swedish french, its meant to be a bosch one but I don't think it is.
Now I cleared the fault out and the car drove fine for a a few days before I started intermittantly getting issues. I had no warning lights but the car felt down on power, whereas normally it boosted at 2,500rpm there was nothing it just reved like an NA car, you could still hear the turbo and the wastegate was working ok. I checked the car for split hoses etc and it appeared ok. I disconnected the battery for half an hour and retried it, it was back to normal for 24hrs, this suggested to me the the fault was electrical rather than mechanical.
After 24hrs the fault returned.
After a long think I decided that I had only been having problems since the maf sensor change, having known the previous owner he had no issues. I have now disconnected the MAF and its running fine, obviously the spanner light and traction control light are up.
Is the new MAF faulty?
Is it possible that there is an underlying fault with the car which seems to be disguised when the MAF is unplugged as the car is running rich.
Any thoughts as its starting to wind me up now!
