ok 2001 gt skip under load just changed plugs cured the problem for oh 15 min no check engine lights just started having iac problems plus i have never changed the pcv just bought the car it has around 80000 miles. i have a bbk cold air 75mm throttle body and pipes exhaust. is it true that a bad coil will not throw a code plus the plugs i pulled out were not wet by any means. bad fuel? sunnoco does use 10percent ethnol and ive heard of problems. [p.s. i am using 93 octain] looks like it was running a lil lean. but im a diesel mechanic so what do i know haha.
