Hi Guys & Gals,
I just purchased a 2007 S3 that has a very bad miss fire. Was hopping it was something easy but doesn’t look that way at the moment.
It has a very bad miss fire and won’t idle or anything, constantly hunting and missing. I have replaced the Coils, plugs, pcv & MAF sensor But still the same.
The car has a brand new HP fuel pump on it which was my next check But does anyone else know anything else to Check? There is no EML on so indicates that it’s mechanical fault really but you still Never know. Other causes i have been thinking could be Injectors, Bent valve or maybe head gasket but it starts first time every time just misses and hunts like no tomorrow.
Any thoughts or advise much appreciated.
