Car still Breaking up in the upper RPM..
Its making me mad about this been to the track this years and the car is only going 106-108 mph and breaking up and studdering from 5400 plus. I have replaced coil,plugs,coil wire,fuel pump what else is there, the opti was done about 3-4 years ago 20k miles ago that is the only thing left to do. Any ideas from you guys or input would be great

Re:
I had a similar problem. My car would start acting like yours in high rpms - It turned out to be a bad o2 sensor. Not sure if that's the problem or not but that's what caused mine to act up. Are you getting good gas mileage?
