ok check this out. my car redline at 3500, i looked and notice that the chassis orginal harnest was cut and different one was replace. All three of them replace. i was wondering is that the reason why it relines at 3500. My car is an OBD1 and my wiring harnest from the motor is OBD1. I think the wiring harnest that got replace is an obd2 because three of the wires were just lying around hooked to nothing.
