So I fell asleep in my car today for an hour with it running and didn't pay attention to the lights being on, I had the radio off and just the heat and lights running. I turn off the car and try to restart and its dead. I have installed a new battery and alternator. We also checked the charging system for a drain when all is off and nothing out of the ordinary. Any ideas?

Thanks

might be idling too low... raise the RPMs a bit to keep system charged correctly

I'm assuming there is an idle set screw on the tb that can be adjusted?

yup i forgot where it is exactly but shouldnt be hard to fig it out
this same problem happened to me untill i raised the idle and dumped in a bottle of fuel system cleaner

I briefly looked under the hood around the tb but unless I was blind, I couldn't see a set screw... Anyone have insight to exact location on tb

It's only an 80 amp alternator. That means at idle you have about 40-50 amps maybe, barely enough to run the car. I had a 165 amp alt and I special ordered it with a smaller pulley to get the amps up at lower rpms along with a deep cycle yellow top ultima battery.

That's a good idea.. how much for the smaller pulley? I also have a 160amp alternator, but does not charge until I'm about 1100-1200 rpm. I idle around 700-800 rpm....

ill look around for a smaller pulley, i was just trying to crank the idle up any way I could, no aftermarket stuff on it so don't have to worry there. I looked up on alldata for an idle set screw and unless I was confused, it seemed to state that the idle was completely controlled by the computer?

just bought this pulley

and according to this link and his calculations

might bump the idle up a little bit for less than $15 its worth a try
