More info on the symptoms. Also note how old your plug wires are and how recently they were inspected.

What's the fuel pressure doing at idle?

Did all this start after the MAF conversion was done?

when did this start? after a mod? like mentioned above, be a little more specific. does it make a popping noise that may sound like exhaust popping? when my maf went out, it would sometimes pop like crazy especially when the car was cold

the fuel pressure is at 35lbs at idle and steady.no the car has been doing it since i bought it and i did the maf conversion and it helped alot but it still does it. it sounds like it backfires sometimes but not that often.
