1995.... 626 question

My teenage daughter's car..which has turned out to be like a boat...a hole in the middle of the ocean whe all you do is dump money into it... She came home the other nite..all the frikken lights in the dash on like a christmas tree..I though it was overheating 'cause the heat gauge was all the way to meltdown about to happen ...spent the whole day at a local Good Year garage here in Miami and they couldnt get the car to overheat... Well she drives to a friend's last nite, only a mile from here and the same happenned, this time though.we left it running and floored the accelerator...Bingo..all the lights went off and the heat gauge back to normal.. What might be happenning here ?? Is It purely electrical ??? and nothing will happen to the car ???

Thanks for any help you can gives us

Miamian with a headache !!!!

Not what "might" be happening... What IS: An electrical screwup of the first water.

My first instinct was "bad ground at device, device backfeeding through dash wiring to get to ground", but that doesn't fit.

Next thought was "somebody dumped a soda in the dash". Nope, that don't fit either...

The temp gauge being pegged - I'd ignore it. It's one of the symptoms. Having it pegged fits with some kind of short, but I can't for the life of me figure what could cause a short on so many separate circuits all at the same time, and be something that revving the engine up would cure...

Computer malfunction? Been struck by lightning while driving recently? :)

Maybe a short in the instrument cluster wiring, or the wiring going to the instrument cluster? I had something similar when the printed circuit board behind the instrument cluster in my Miata got damaged.

Both times the problem was a night when she probably had the lights, radio, and in Miami, the AC going. You may have either a loose ground, or a partial ground. Check the grond wires going from the body to the engine block (alternator) and the battery. One of them may be crudded up or marginal.

Seen simialr behaviour on the instrumetn cluster on some GM with leaky valve cover gaskets. The gread buildup on the ground wire cause spurious signals that gunks up the electronic instruments.
