Acting like one cylinder firing lean.

Do a compression test to see if one cylinder is lacking.
Also you could point a lasertemp gun at the same spot on the header tubes on each cylinder to find out which one is running hotter/leaner.

How/where is your pcv hooked up?
Put a temp gun on it but pointend it right where the first bend coming off the heads. Just read I should check at a straight line of pipe. also did it when car was off which I know isn't correct but I had an average of 145* on all but one at 115*. Leaner burns hotter so what's up with that? Lol
Will do a correct reading sometime this week after work.
