Had a problem Fri. night

[Buzman23]

I was at 1320 on Friday night and everything was going great. I was hanging out watching some runs and even running a few times myself. I ran 5 or 6 times none back to back but the problem was on my last run.

As I was pulling around to the beginning of the staging lanes my SES light came on and I noticed that my voltage had dropped to around 10V. Well I had to keep my RPMs up and I had a hard time staging but I made it through the run (and lost to a 2002 Z28 :thumbdown: ). My car was fine as long as I wasnt sitting still in drive in that case I would drop RPMs to about 500-600 and the car acted like it wanted to stall. I drove home and Sat. morning it was still doing the same thing. Then Saturday afternoon leaving the golf course everything went back to normal. :wtf: Any ideas on the cause? Thanks for any input...

got to get your hands on an OBDII diagnostic scanner so you can see what the SES code was... Id call up autozone and those places to see if they have one you can use at the store.. I was about to buy one for ecu and obdI and II pcms but do to recent explosions in the drivetrain I didnt.
What ZDriver would do-
1.) Buy actron diagonstic scanner use it and return it for money back if nobody will let u borrow one.
2.) Check alternator (when it starts to die you have to rev higher to generate more power). If the problem starts again turn on your lights to see if the dim at idle.
3.) Check coil grounds on each one of your coil packs (I think each pack has its own ground unless they are in series to 1 ground?)

Best of luck man keep us posted..

Yeah pull your codes. It also may be something wrong with your spark sometimes an arcing plug wire causes it to act like its going to stall.
