I'm having a bit of a problem. I'm experiencing a very hard brake pedal when shifting from reverse to drive and I hear and feel like a rubbing/vibration on the brake pedal. VSC and Trac off lights up then it goes off.
Just a few hours ago before this accured I disconnected my battery to acces the low beam bulb to convert them to hid's. Put everything back in place, started up with low idle, reversed out the garage and put it in drive. That is when the above mentioned accured.

Any help is appreciated. Thanks.

 

Hopped in awhile ago and started it and right away at warm up it is idling below 1000rpm. Drove it around the block and feels like it is lagging power. Parked in the drive way and the rpm is a little below 500rpm and feels like the engine is gonna shut off.

 

Must be normal eh? Mods please delete this thread.

 

HID's you say?

Does it happen when the lights are not powered on too?

Have you tried putting stock bulbs back in it and eliminating the ballasts?

I have never personally heard of them causing this sort of issue, but they are a small transformer and I'm sure they put out some sort of RF noise, I suppose there could be SOME chance one of them is causing some sort of interference with a computer system somewhere? I know I've read about some cheaper ballasts causing noise through the radio.

I'd at least try unplugging the ballasts as a test, just to eliminate them. Might have one too close to something that's sensitive to electrical interference.

 

I reinstalled the factory headlamps and it drove normal. And just yesterday I put the aftermarket headlamps with hid back on and seems to be okay this time. Thanks for you input though.

 

good deal; glad you got it figured out

possibly just knocked a plug loose or something on the first go-around, and when you got in there the second time you nudged it back into place

gotta love working on newer vehicles
