High RPM missfire
Hey guys,
I am wondering if someone could help shead some light on this.
I have a LS/vtec with a B18c head. the thing runs like a dream from idle to about 6000RPM but from 6000 to 8000 there is a very slight missfire. Not bad but it is there. the ignition is stock. The air fuel mixture is good. the motor is run off a chipped p28 but i know thats not the problem I swapped it with another p28 and it did the same thing. Anyone have any ideas?
Thanks
