I have a miss that happens when I try to accelerate normally. But if I push the pedal slowly and keep a gentle rate keeping with the motor it'll run as high as I want to go. But at any point in the rpm I push just a little to far it will miss.
Computer is new a has been checked all plugs,wires. It's been to two Mitsubishi dealers one had a guy whose worked there 17 years and tried for two days and didn't charge me a dime for trying to fix it.
The other dealer hooked it up to the big computor and it didn't show any codes.

Help me I have a Z06 to race.

 

Hmmm... well actually change the plugs with good ole NGK classics. None of this expensive crap. Also, change the wires with the Mitsubishi wires.

You run it on premium right?
