I need some help here with a diagnosis for my poor baby.I noticed a while back that when I depressed the clutch all the way, like coming to a stop light, the idle sounded low and the car would die down a little, like it almost wanted to stall. I didn't think too much of it, wrote it off to an issue related to the rattle in my timing chain.Anyway, the other day I was driving downtown and my electronics, stereo, clock, etc went out for about 1/8 or 1/16 of a second while I was driving. This happened intermittently 'till I stopped the car. Once stopped, she died, and had hardly the power to roll the windows up. There was no restart, and no click even on the jump attempt. So here she sits, and my thoughts are:dead batterydead alternatordead startersecurity system freaked out and killed the car

Does anbody recognize these signs or what they could mean.We'd both appreciate help

Thanks

that sounds like it could be your alternator and if its not that then get your battery checked it sounds like your battery is bad you I had the same problem where I couldnt hold idle when I would come to a light or stop sign you should get that checked first so you dont have to pull your alternator if its not that.

And your question about the electronics going off check your accessory fuse it should be a 10amp fuse its in the kick panel next to your clutch pedal.

Hope this helps

Your problem sounds very familiar to a problem I had that happened only once and lasted for about one minute and then it was fine.

I was coming up to a red light on a cold day and pressed the clutch and the brake. I had the heater and the radio on and suddenly everything went completely dead! I was unable to roll down the windows, turn on my flashers, brake lights wouldn't shine. The car was absolutely and completely dead! All of a sudden the car came back to life after sitting there for a minute and I started it back up and was on my way. This happened about 4 years ago and it has never happened again.

I'm sure it was a computer issue or something froze up or maybe even thawing ice water had something to do with it.

Good luck finding out what your issue is. I'm interested to find out because it seems very close related.

OoOOOh!! check your alternator connection! Something like this happened twice on me. The main wire fastened to the back of the alternator had apparently reached thermo-nuclear temps and melted off completely. I don't know why it got so hot, bad connection I guess.. but yeah, one night coming home from college I noticed my stereo was too quiet, my lights were dim, then it died.. I went to a buddies house and put an ohm meter on everything i.e. alternator, battery, connection at battery, connection at alternator, etc, tests with the car running and off to see if I was losing voltage anywhere.

I'd ran my battery to the trunk with a one-piece 4gauge cable for the positive and just grounded the chassis back there. So I didn't have a ground going to the block itself Anyways, I ran a 4 gauge to the block from battery, replaced EVERY single wire going to the alternator with shrink-wrapped connections and coated with di-electric grease and haven't had a problem ever since.

That's just me though. If your car gradually lost volts then it's either the battery or an alternator/alt. wiring problem.. Or your alternator belt snapped unknowingly.

I had a weird problem when the glove box opened. It would blow my courtesy light fuse which also took out my clockand radio and always said the door was open. Eventually the glove box had to be wedged closed hard or it would blow. Real weird. I don't have that car anymore cuz of rust. /rant
