Hi all. I have a 93 Chev Lumina (car) that stalls out. It acts as if the a spark plug is grounding out and sems to lose spark. After it dies or has been sitting for a while, it it may or may not start. 10 minutes later, it'll start and run great for a few weeks. There is no rhyme or reason to when it dies, and I cannot duplicate the problem... that's why this is so frustrating. I 've even towed it to my mechaninc twice, after I have looked for broken wires,etc, only to have it start when it gets there.
I have changed all of the spark plugs and wires. When it does stall or won't start, I crawl underneath and wiggle, move, twist, and swear at /on every wiring harness that I can find...I can't find one that allows the car to start. Then after a while (5 minutes and up) and SEVERAL turns of the ingnition key, it'll start and runs great until next time.
So, my question is, is there and inherant problem with the lumina's that I may be experiencing, such as an ignition switch, ot fauly connector? Any thoughts?
At this point, I feel that I'm going to have to start buying and replacing parts. I'd like to narrow it down a bit first.
I would greatly appreciate any feed back.
thanks
