Continuing saga on my jeep is: I did drain the fuel tank as prescribed above. That worked very well. Had about 7 gallons of gas in the tank. I then replaced the fuel filter, added Lucas Fuel Injector cleaner and HEET to gas tank and filled it with fuel.
I drove it about 3 blocks and the engine died. The ASD fuse had popped (30 AMP). I had a spare 50 AMP and put it in and the Jeep started. Of course it threw off a SES code indicating something was wrong with the ASD Circuit, which I'm guessing is caused by the fuse popping.
The engine will idle, however it still has a miss in the engine, even with the new gas (I only got to drive it about 6 miles before I got called in from my play time
). At higher RPM the engine does seem to smooth out.
All the gauges are working, engine temperature is normal, oil pressure is 45 - 50 lbs, alternator is about 14.
I'm thinking I'll take it out for a drive to see if running it will improve the idle. But I doubt that it will.
Any thoughts or ideas would be much appreciated.
