Need some help guys, My throttle body has been sticking, so I took it back to the dealership (for the third time), they said that they cleaned out the throttle body and adjusted the throttle body, (I guess they adjusted the throttle blade) but anyway since I got it home, when I am at a red light it surges and the idle is ruff, the rpm's are around 400, just wondering what it could be, maybe the TPS. Any suggestions would be greately appreciated.
Thanks,
Jason
