Hi I have a 92 5.0 mustang convertable with a few issues. The car boggs at low rpm under acceleration and then bursts with power most of the time. Sometimes it boggs then backfires and accelerates. When i pull over for a few min and then restart the car works fine for a min and then the same problem occurs. put new plugs, wires, tps, and replaced all vacuum lines. The car has no Cats,egr. Has longtube headers and cold air intake though. If Anyone can assist Please Help.... Very frustrated..... lol check engine light came on once and car worked great, then took a break and restarted. check engine went off and car worked like **** again lol

 

Does this happen all the time, hot cold? have you checked timing and fuel pressure?

 

have you tried replacing the tfi module or coil

 

LoL it was my o2's, there fried. Unplugged them and no bogg
