Backfire issue!!!!!!!!!!!!!
Wednesday, November 07, 2007 7:21 PM
Hey guys got a question, my car is dumping a rediculous amount of fuel into my motor. It already fried out my cat, ngk plugs and o2 sensor. And its still doing it and I can't figure out why any ideas???????
This is either what is new or was just checked
Fuel Filter
New plugs
Both coil packs
Boots
o2 sensor
computer
timing was just redone
coil pack cover
full 3" exhaust
cams are fine
And it is doing it on all cylinders not just one so I don't think its a valve please help out as much as possible I really appreciate it thank you.
