Erratic Idle and stalling. Cleaned throttle body and fixed the problem.
Tractoin and check engine illuminate and the car speed and power goes down. I try to disconnect battery and both light went off, unfortunately it comes back later.
TROTTLE BODY HAD ISSUES THAT EFFECTED MY BRAKE SENSOR AS WELL..
