lately my headlights have been acting funny at stop lights and when idleing, the volt guage jumps from 13-14-15 while your sitting still at night, had a cam put in a couple weeks ago and i think this could be the cause?? don't know how? but maybe because thats about when it started, the cars only got 10,000 miles could it be the batt, alt or belts?

 

Do you have smaller pulleys mod?

 

If the car is idleing lower after the cam swap it could cause this. also check your main ground wires.

 

yeah i got a asp underdrive crank pulley & and a asp overdrive alt pulley since it had 5000 miles, with no problems at all, i had the cam put in around 9000 miles and thats about when it started doing this

 

no, now she idles at 9500 (?)
