timing issue 92 Cherokee
92 Jeep Cherokee 4wd, 4.0 motor, automatic. Several things have been done recently, new timing chain, coil, distributor and cap, map sensor, computer, cam shaft timing sensor. motor now will start and run. It runs well at idle, but the timing gets all out of whack as the RPM's increase. Is there a knock sensor on this motor, and could it cause this? If so, where is it located? Any other ideas?

Re: timing issue 92 Cherokee
Not sure about the knock sensor.
1st thing I'd re-check would be the timing chain installation. If it's off by 1 tooth / even slightly you'll have problems. Also, check the vacuum hoses. There could be a vacuum advance on that engine but I'm not sure.
