what's the major malfunction?!?!

[grease monkey girl]

ok, so I changed the ICM on my attention whore and that didn't solve my problems. so what the car is doing now is this - it idles great at cool temps, but the minute the fan on the driver's side kicks in, my rpm's drop and in idle, the engine wants to die, I have to shift it into neutral before stopping or I will die. It seems that the problem is in direct correlation with the fan. The fan on the passenger side of the car does not seem to be turning on at all. On top of that, I put ANOTHER new ignition coil in it and THE NEW ONE IS SPARKING, TOO. I replaced the spark plug wires and about 20 minutes after running the car, checked on it, and it looks like a neon light show under the hood. This is the 3rd coil I've had in there, the second set of wires. WHAT THE HELL IS GOING ON!!!!!!!!

damn well i have no idea whats goin on mabye your wole dizzy assembly and ignition are all shot?? just a thought

Depending on what year the car is. It sounds like you may have a bad Coolant temperature sensor. This is what sends the message to the computer as far as the vitals of your coolatn preassure/temperature. If this sensor is bad it can sometimes make the car run horribly.

I had a problem with my new high performance coil (accel) i put in my 85 camaro, sparked to. What i did was buy some electrical cleaner, sprayed all the electrical connections, and the new coil. This solved the problem of the spark jump from the coil.
If that don't work, check your secondary module next to your coil.
Your fan problem sounds like your idle speed is retarded. Check your timing and see what its running at, more likely has to be advanced. The passenger fan not kicking in, might be just a fuse check your fusebox, then check your electrical connections running from your fan to your control module, when you have a positive send to your drivers side fan, your passenger side should to. Use a test light for this.

The rpm dropage is normal when your fan kicks in depending on how many other accessories you have running. If your pulling alot of volts with a stereo system (for example), this will cause your engine to drop in idle, but it should build back up to approx. 600 - 800rpm while sitting still (idle)

The coolent temperature sensor won't make to much of a difference in "badly running". If this sensor is faulty your fans will be turning on and off irradically, or even not turning on at all causing an overheating problem.

I think the passenger side fan comes on when your using the AC only usually. Mine doesnt work at all and I havent bothered replacing it because the car doesnt run hot and my AC doesnt work anyways.

well, the passenger side fan came on beofre all this crap started happening and my a/c doesn't work. the formeer owner told me that one fan kicks on for block temp and one kicks on for water temp. of course he might be drunk or retarded, that's still up in the air

Let's think about this a moment. The coil produces High Voltage to the spark plugs so if the coil is producing too high of a voltage, arcing will occur. My best guess is something wrong with the voltage regulator supplying too high a input voltage to the coil causing the coil to arc. Take a voltage measurement off the regulator to make sure it is O.K. Remember the alternator puts out about 16 volts and this has to be regulated down to 12 volts, although its only 4 volts difference , to a coil thats a lot.

Try pullin all your wires off (one at a time) and cleanin them with electrical parts cleaner, and then using die electric grease when re-attaching them.. it should stop your wires from leaking..

[grease monkey girl]

you guys are the best.

[DaMoNe6969]

yeah.. thats what they tell me!

[grease monkey girl]

who is they? your'e parents? they don't count. lol I'm just playin with ya.

[DaMoNe6969]

ever figure out what the problem was?

[DaMoNe6969]

they dont?? well.. that sucks

[grease monkey girl]

well I'll say you're in the top 10%. does that make you feel better?
