OK once a day, when i am at the light, the dash lights begins to dim in and out of the led! The D5 mainly. The car begins to idle a little rougher however the RPMs dont change one bit. I can feel the car shaking under the brake pedal. ie the brake pedal feels a slight humming to it, and then it will go away. I am takin it to the dealer on tues, but was wonder if anyone know wtf this is?
Thanks

 

check your coil connections, Do you feel a loss of power at top end?

 

try the throttle cable... maybe it needs to be tightened for slack on idle...

 

No, I'd be willing to bet it's the positive battery cable loose on the terminal. That happened to me after I forgot to re-tighten the thing post- CAI install last fall.

 

Thanks guys i'll let u know when i get the car back on weds!

 

Well........u guys were all WRONG! Its called a new tranny!

 

Oh Lord not another!!

 

Who cares....7 year/100K....beat on that tranny...make sure its dead and replaced by 90K...

 

sounded like a muffler bearing to me
