Recently I noticed that my car idles at 500 RPM but at night, with the headlights and interior lights on, the car idles at 900 RPM. I had the battery checked out and the battery is fine.

My car is a '99 with 34,200 miles on it so I'm thinking it isn't the alternator that could be the problem... but then again I did get a system installed about 4 months ago which could contribute to the alternator being the problem.

I'm wondering what the problem could be? I was thinking the alternator could be the problem... or maybe the timing needs to be adjusted?

Feedback on this issue would be much appriciated...

 

Thats about right for idle. :dunno:

 

yup

 

when your car is under load, the car is suppose to idle higher. its normal!! that's the duty of the ELD (electronic load detector)

 

Yup, I forgot to mention that in my post. If you turn your AC on, the car will idle up too.

Thanks!!

 

Well... guess I was concerned over nothing. Thanks for the feedback everyone.

 

its your stock foglights,..they are messing everything up,..i suggest you take them off and give them to me

 

:no:
