95 trans am lt1 6speed backfire under acceleration and stall when warm
 
hello guys new here,... I have a recently rebuilt motor with weird issues,... bought it from a guy who had it rebuilt by a shop,....no I havenít checked fuel pressure but I have replace optispark and coil, everything is wired up right spark plugs not in bad shape, maf is working fine, what itís doing is run fine when cold at idle but under acceleration it pops from exhaust and when it warms up idle wants to cut off or stall, I had unplugged whole passenger side injectors to find idle problem but seems like it doesnít change so really scratching my head,..... need help please!

Have you had the ICM tested? Did they heat it up good before testing it?

How old are the O2 sensors?

Scanned it for codes?

I'll delete your other post, and my response on the 14-year old thread.
