You always seem to have an answer so ill ask you: my car stutters when hot between 2k and 3k rpm. It also wont rev to redline sometimes. The exhaust will pop and itll feel like hitting redline. I have plugged in an obd reader, tried a new cam sensor all to no result. The car is stock. Ive cleaned my throttle body and vvt solenoid. I will try unplugging the vvt solenoid connecror and see if it is a vvt fault. If not, do you have any ideas? Also, belt not due a change until next year or 10k more miles.
