88,

Spelling and diction aside, the electrical gremlins are probably not related to the coolant temperature sensor leak, unless the leaking coolant was spraying on the alternator. If the alternator brushes and slip rings were coated with anitfreeze, and the coolant began to evaporate, the resulting mess would be a sticky solution of coolant that could prevent the alternator brushes from seating properly.

What is the system voltage when all the light dimming is going on? If the alternator isn't charging the battery, you might not be able to run long on a failing battery.

Check and clean all connections, and tet the alternator output. You can do this on the car if you have a voltmeter and a small screwdriver.

Sorry about the mistakes. My computer was so slow that night taht i typed that whole message before it even registered and displayed on the screen. Normally I am a pretty good speller. But it very well could have sprayed on the alternator. But its wierd. My car doesn't idle well and my radar detector resets when i let the rpm's drop. Any suggestions

I count 12 errors, but I'm sure I'm guilty of even worse, since I usually type faster than my brain can compute.

Anyhow, the reason the car stalls out and the radar detector resets is because they are all 12V acessories. If the ECM, Injectors, and ignition coil don't get the full 12V, they don't operate properly, and thus the car stalls. Same goes for the radar detector (except for the stalling, it just resets, in case anybody got confused).

It could either be a battery problem or an alternator. Vader mentioned about the small screwdriver, and I think I know what he is getting at, but I don't think you can "full field" a late model alternator (I could be wrong, but never had to). Don't rule out the battery, because it takes electricity to make electricity, and if the battery is shot, the alternator will not put out, so get them checked out. Good luck.

Mine is acting similar, but I know it isn't electrical. A few months ago, when I had my injectors cleaned, well, I guess my Fuel pressure regulator rotted out, or something, cause when I put it all back togather, it was still hard to start cold. So I re-ran the checks and found now the fuel pressure regulator was blown (or it already was blown, but the injector leak was overshadowing that problem) So now my fuel pressure will drop to say around 33-35 psi...barely idles, lights dim, radar detector resets, CD player keeps on trucking though! Sometimes the car stalls. I has been getting progressivlt worse, as I assume the hole through the reg is getting larger, and allowing my fuel pressure to drop even lower. If I recall correctly the service manual says that lower than 24 psi the car probably wont be able to hold any idle, and just constantly stall.

So what am I waiting for? Well, my Tax return, since I'm not working yet, I have very little money, uncle sam should come through for me in the next few weeks, and then I need to find a good AFPR and use the 10% summit discount we get

Oh yeah, my coolant level sensor is also busted...just not leaking (that I know of) so my car always tells me I am out of coolant...Just too lazy to replace it/find it

If you think that you will be able to fix your problem w/ an AFPR, I think you will be dissapointed. Many of the AFPRs DO NOT come w/ the diaphram, and this is the part you need. Granted, its a good idea to get an AFPR, but you may need to purchase the diaphram loacally. Good luck.

So you mean that the AFPRs that you buy from Summit, Jegs, etc. are just the "top hat" with a screw/bolt through them?? My God that is ridiculous.... the internals can be bought at any parts store for $22-$25, the whole shebang can be bought at the dealer for about $150... making my own is looking better every day
