The entire ignition system is pretty much brand new. Nothing has more than a few thousand miles on it. EXCEPT maybe the coil. I don't know if that was replaced when the previous owner was trying to figure out why it wouldn't start. They basically kept throwing parts at it until I bought it and replaced a relay.

This morning it happened again. I noticed another symptom that I completely forgot about previously. When it's running shitty and the brake lining light is barely lit the temp gauge doesn't move. Could all of this be caused by a faulty coolant temp sensor?

Uh... I think the car will still run with that sensor unplugged. I don't know if unplugged is the same as reading max cold. Simple enough thing to replace though. Maybe something is grounding out somewhere? The clutch fan is known to eat stuff. Not sure there's anything around there that would cause your issues.

Yeah it'll run without that sensor, but it runs like shit. It's doing the same jerking that my white one did when one of the sensors was bad if I'm trying to maintain speed. It was fucked up my whole way to work this morning except for about 30 seconds when I was right across the street from work. When I downshifted to hit the u-turn my temp gauge flew up to where it should be, the brake lining light turned off, and the engine ran perfect... For 30 seconds.

have you checked the grounds behind the cluster? Try smacking the dash above the temp gauge and see what happens.

No I haven't. That's a great idea though. I'll try to remember that next time it happens.

Tried smacking the dash, that didn't work. I believe the problem lies with that loose wire on the starter that causes it not to start from time to time. Last time I had the problem I left the car running when I got home, popped the hood, wiggled that wire, and the brake lining light was out when I looked back in the car. Can't be 100% sure that's the problem though until I can get someone to look at the dash for me while I wiggle it to see if the light goes on and off.

uhm... As fun as that sounds... I think I'll pass. :-P

One of these years I'm gonna get it back up on the lift and start fixing stuff. Having a charging problem now too. Oh the fun of owning an old car.

maybe dumb question, but if you know the wire is loose why not just tighten it up and see if the problem persists?

Good question... Without removing things I can barely get my arm in far enough to just wiggle the wire with my fingertips. To actually be able to reach it I either have to get the car up on a lift (which there are none available at my job right now) or remove the air box and several hoses and possibly brake fluid reservoir.

throw it up on some jack stands. I swapped my starter out in like an hour taking my time on stands with hand tools. All you need to do is get a wobble socket and some extensions on there to crank it down.

I'll fix the wire when I swap out my alternator. Fucker is almost dead, putting out just under 10v at idle and just under 13v at high RPM. Wasted $30 on a trickle charger at Sears yesterday. When I got home there was still enough juice left in my battery to start my car back up. Put on the trickle charger over night, came out and it said battery was full... Battery was fully DEAD! Thought maybe battery (which by the way is brand new) was defective, but when I got to work this morning I disconnected the negative terminal and the engine shut off immediately, so even if battery is defective the alternator still needs to be replaced.

Damn you! lol. The only time the temp gauge ever not worked was when I was having all the other symptoms. Now after smacking the dash like you suggested it likes to stop working randomly until I smack it again.

I did fix all the other symptoms though. Pulled that wire off the starter, cleaned out all the corrosion, filled the connector with dielectric grease to prevent future corrosion, and all is happy since. Well, all relating to that is happy. Mucho other problems.

lol, so pull the cluster and tighten the grounds. If smacking it knocked it loose it was already loose, and probably just held in place with dirt, haha.
