mis and cutouts at high RPM's are usually coil or opti. Go to Shbox.com and do the opti test to see if that is your problem. I think most advance auto and auto zone's can test a coil to see if it is ok. Hope this helps!

I changed the opti connector cause the wires were bare but that didn't fix it could it be the computer or the transmission??

Hopefully you find your prob as I have been chasing a high rpm prob for a few months now....

Check the cheapest things first and move on....

Plugs
Wires
Coil
ICM
Opti

I don't know if the PCM would do that but if it can I guess I need to check mine too...
