Alright here are the symptoms: A bad hesitation above 4k and what kinda sounds like a backfire. It runs fine under 4k. Its also real hard to start in the morning, and it idles pretty rough sometimes. Any ideas? I just changed the plugs/wires, oil, and fuel filter so where should i look now?

 

check the coil, coil wire, and the opti. those three things usually cause high rpm misfires.

 

Possibly your fuel pump is on the way out.Check the pressure.Also,hows the filter?

 

Burnt wires ? Loose plugs?
