What does that ALL mean?? My idle is ok, until I turn the headlights ON...then it starts to struggle. It doesn't do this when the car is COLD. When the car is fully warmed up and I turn on the headlights, the idle struggles. Also, I noticed while sitting at a traffic light, that my headlights dim down a bit IF I HIT THE BRAKES...I can see my dash lights dim down too. Any ideas what the SOURCE of this problem?

 

Can you spell "Alternator" (or is it "Alternator belt" ?)

 

I don't agree with the alternator. I say it's the BAC components. When you turn on accessories under load the BAC she kick on and raise your idle to compensate. Your problem is either: 1. Bad BAC 2. Bad BAC connector 3. *MOST LIKELY* fried transistor on the ECU.

Does your idle drop when you turn on the A/C also? If so, that's a sure sign of a BAC problem. Do a search on the forum for BAC fix. I've done it. It's pretty easy. Message me if you need some help.

"She kick on…" hmmm, I sound like a mad Frenchman! "She kick on, no?!? Mon Dieu!"

 

Take your BAC off and clean it throughly with throttle body cleaner. Then spray it with WD-40. Then put it back togethere and use the adjustment screw on it to fine tune it.

 

I put a good used BAC valve on couple weeks ago, tested properly for the Resistance checks. I also got a new alternator belt and its on the car pretty tight. I will investigate this ECU problem a bit further, in the meantime any other things it could be?

 

The diode in your alternator. But these other guys are probably right.

 

I would say alternator. I don't know about the accessories. But dimming of lights when you hit the brakes & when headlights are on sounds like alernator or battery problem. Maybe there is another problem for the idle. My idle is real high, but I get the dimming. I am going to fix that today.

 

I used to have that problem. It was so bad after adding an electric fan that the radio would turn off when I hit the brakes. Solution?

I put an FD alternator on. No more voltage issues!

i had the same problem. I added a ground strap from the chassis to the engine block and my problem was solved
