When I drive with my AC on and the headlights are on the car begins to hesitate and bucks when im driving in the city with normal driving conditions. As soon as i turn off my headlights with the AC still on, the hesitation and bucking are no longer present. Any ideas on the cause of this problem? Thanks!

 

Maybe low voltage or ground loop issues? Have you checked your battery, ground cables, and battery positive connection lately?

 

If you have a power FC that could be the problem, I believe you have to do some re-wiring.

Try a ground strap. Works like a champ
