OK, here is a good one for yall. The other night I was heading on my first extended road trip in my z and somthing happend completly baffels me. When I turn on my headlights my engine seems to go through cycles of getting fire then not getting fire. This is while the gas is applied at a steady amount, it just runs then dies then picks back up and dies again at even intervals. The battery has plenty of juice to start the car and it seems to run fine without the lights on. Am I lookink at a bad alternator here? If so, I have never had one act like this. FYI i am running a zx dist with a gm modual that has been working fine, so I don't think thats the problem.

Thanks,

Dan

Yep, sounds like you have charging issues maybe as simple as dirty or corroded battery cable. Years ago mine acted just like yours and it was a bad alternator.

With the car running.Take a screw driver and place the metal end on the alt. Then put your ear over the other end.

If the alt has bad gears or bearings witch would couse it to foul up. You will here it.

But dont get your head stuck. :tapemouth
