i just got my car alarm and keyless entry installed on my mp3 and afterwards the check engine light was on. as im driving it flashes on and off. guys at best buy who installed the alarm said they had to remove a bunch of wires from a previous alarm system that was no longer there and that might have triggered the check engine light. there shouldnt b anything mechanically wrong with the car, i just wanna to turn off the light. anyway i can do that without takin it to the mechanic?
