Long and short fuel trim is at 100%, timing advance is at 38 deg at 25-2600 rpm. I know the timing is off, the car sounds like a lumpy V8. The timing is off by only one tooth, I just cant seem to guess which one it is. Gonna try and fix it, but since the guy is coming to pick his car up tomorrow - and knows the timing is off, and if I did not have time he said not to sweat it - I might not. Oh well. Anyone go through something similar??
