been having a rough idle issue with my lgt. i had a lw crank pully on it and i heard it skewed misfire codes. so tonight i pulled it off did a log will doing so, cels came on again 2-3-4 misfire...
car has 60k stage 2 brand new ngk plugs (miss was before plug install)
just cleaned maf.
swapped around injectors (problem seems to move around the cyl like a loose child in a mall) one log its no 2 next its 3 or 4 with most of the misses..
misses/rough idle.. rough to about 3k where my butt doesnt feel it and the log shows no roughness. so im assuming a low rpm issue only. car pulls like a raped ape and no non normal sounds..
done some searching
heres another log. till line 350 no misses.. while driving. the first run to above idle was a full throttle full boost 1-2 to 4.5k no misses al all while in boost. now it seems its no load missing wtf? ideas?
