My car has the PATS security system. When I try to start the car and the theft light flashes rapidly the engine will not fire. If the light does not flash rapidly the engine cranks up instantly. When it does start I'm getting a cylinder misfire code and have gotten a EGR valve code. From what I've read the problem points to a PCM problem. Does this seem feasible to anyone? If not, any other suggestions? Thanks in advance.
