HID's installed, now car stalls
 

My bro just installed some HIDs from a new Cadillac STS into his Maxima. Now when he drives the car will "buck and then stall out." The HIDs work fine. Could this be related to the hids?

I wouldnt think that HIDs have anything to do with stalling out. Even if they are drawing too much power they wouldnt make the car stall. Did he check anything in the car? Did he fool with anything when installing them?

Difibulation modulation.

Sucks when that happens after HID installs.
Make sure the tubes are clear of any unused blinker fluid.
Check the tire pressure as well.

Does the car buck with the lights on and off as well?
