I have a 95 intrepid with 3.3l engine and 78000 original miles. The car has been very reliable until just recently. It starts normally and runs for first few minutes then begins misfiring and stalling. Engine will start back up but appears to be running on 2 cylinders. Converters get very hot during this time. Fuel pressure hovers between 36 and 40 psi. I have replaced crank sensor, cam sensor, throttle position sensor, spark plugs, coil pack, fuel pressure regulator, and all the relays, yet the problem persists. Not getting any codes. Really stumped by this problem maybe a bad ECU? Just want to see if any one else has had this problem and if so what was their solution. Really need to get this car back on the road.
