I was driving my 1997 Chevy Lumina to Arkansas when I noticed the service light on. I stopped by an Auto Parts where they hooked it up to the machine and said it was a sensor. I proceeded on my drive when I noticed the car missing as I accelerated. The car wanted to die everytime I went up a hill. I put the car in drive and it did much better. However, it died going down a hill. It would start and idle fine, but when I would step on the accelerater it would die. The mechanic at the Fort Scott garage said the computer went out and it would be over $700 to fix. I seem to think it has to do with the fuel lines, injectors, pump or something of that nature. I had just filled up with gas before it began missing. I did dump some gas treatment in the car. The mechanic did a test on the fuel pump which read that it was fine (40psi?). He also said the fuel injectors were fine. I guess I don't understand about the computer. Would it act like that? or just quit and not start anything? We couldn't get it started for the last day and then today it started and sounded horrible. I am afraid of starting it again and ruining anything else.
Does anyone have a suggestion? Oh, I did replace the spark plugs a few weeks ago and the fuel filter because it was stalling at lights and low speed.
