On what u guys think this sounds like. When car is in boost some times it works perfect other times it works bad. What it does is it is almost like a little pulsation , or kind a like a faint buckin almost,or slugish if u want acall it that too!! And when it does this my pyrometer goes right down to 15 or 1600, that means the car is running lean right??? What all can cause this problem??? Im thinking its still the o2 sensor i just put a new 1 in a bout 3 or 4 weeks a go. What do u think it could be causing this?? If i can just get this figured out it would be great thanks guys!!!!
