help!!!!!!!!
91 l98 spd. been running great then all of a sudden, coughs and backfires in intake, barely runs when you try to go offidle,,, cap rotor and timing are ok and it seems it does this when it goes into closed loop, almost as if leaning way out!, ecm is about a yr old and was tuned about 300 miles ago, new fuel filter and injectors,, like i said was running perfect till all of a sudden?????? any hints as to what may cause this, im no car dummy but i am a little lost on this???????????????????? thanks in advance

oh and by the way no codes or ses lights. just dies and backfires the second you try to rev past idle whether car is sitting and its even worse when you try to put it under load.but it idles fine!
