Well I finally come to the conclusion it was my injectors. Shortened the spacers and now it idle's like a champ! Simple qick fix. I just hope i didn't shoten them too much. Can there be too much pressure down on the injectors?

do you think that not lubing one o-ring would cause my idle to drastically drop after hitting the clutch while driving? it only does this occasionally - typically when clutching in after a higher engine load (more after engine braking than acceleration). it'll drop to 300rpm or so & then back up to idle-ish.

this discussion reminded me that when i was installing the engine, i had to replace the #7 or #8 injector & i didn't know that the rings needed lubing.

absolutely, mine would drop so hard at deceleration sometimes it would just die. really annoying. I didnt lube them, but tightened them down and no more idle probs at all. Try lubing them, its gotta help
