Ok this is all the things that i have done to my rig:
check cam timiming
adjusted throttle position senser (as check engine light resuested my too)
The problem is she lacks power, After pulling the codes she got better but when she is cold, or when she just gets a bug up her arse she runs poorly and acts as if she is not getting enough gas, checked fuel pressure and nothing abnormal there, after she warms up she will run fine for about an hour or so then without warning she will act up again, any ideas?
Also backpressure measured fine at the tail pipe,
If motor or head gasket was bad wouldn't the problem be constant and not intermittant?
Also please be specific in your reply as i am not that mechaniaccly inclined but i do learn fast [img]images/graemlins/confused.gif[/img]
