Ok this is wats happenening and it will only do this after the car has warmed up. Between 1000 and 3000 rpms, the car sputters and kinda bogs down until after 3000 rpms when the car picks back up and continues normal acceleration. Iv replaced wires, plugs, cap, button and anything else i feel could cause this problem but the problem still persists. If anybody has any suggestions please let me kno, thanx.

 

Bad map maybe..

 

Check for a vacuum leak and the fuel presure regulator, both can cause your problem.

 

timing is everything.

 

Hey, try swappin a different O2 sensor in, but I think it really could be a vacuum leak, doin a vacuum leak search will only take at the most 15 minutes. It's worth your while.
