Re: 347 timing problems
Ok Im assuming you have set the BASE timing correctly, ie set the ecu to self test mode.
Whats the tps setting at?
Firstly check the tps setting. should be 0.7 volts.
if you are still having idle probs, with the ignition off, disconnect the ISC start the car with out touching the accelerator, & wind the screw in to achieve the correct idle speed. Turn eng off & reconnect idle speed controller.
If you havent set the eec to self test mode you are setting the timing wrongly.
