I have a 1991 Lumina(3.1), that has been running like a champion,, then out of the blue one night, I reversed out of a parking spot, the idle dropped and she died out. Restarted, but had to give gas to get going,,, then went on driving like a champion. The next day, i went out and drove for about a mile and the speedometer went to 0 and had a higher idle. I just kept on driving and the speedometer came back and it went back to normal. I drove some more and it happened again,, speedometer failure and had to keep the car in neutral at stoplights and rev it up so it wouldn't die. Made it to my destination, parked and when i came back it started right up like normal. Driving back home, the check engine light and the speedometer went to zero simutaneously... then came right back. Made it home, and put it in reverse and it died. The engine was hot, the radiator was cold, and the fan kicked on. It's not the thermostat and i don't think it's the water pump. I'm just baffled - any ideas?
