Answer
Hi Harry:
I would check your ground wire connections at the engein to transmission mounting bolts I have seen bad ground wires on these cars cause all kinds of wierd conditions. look at the wires and make sure they do not look green and corroded. grab each wire and give them a tug you may find one is just hanging on by a thread and causing your issue. If you have replaced the cam and crank sensors you need a scan tool (not a code reader) to relearn the cam/crank corolation. Make sure the engine throttle plate is clean and free of carbon build up along with the Idle control motor and the bore it moves in in the throttle body. Any secuirty lamp come on when it starts and stalls out right away Does the lamp flash? that would indicate an issue with the factory security system. what O2 sensor codes sets a heater code or a performance code? rich/lean code??
