My car is miss firing. I hooked a timing light up to it and when i looked at the crank, it was like it was jumping marks. Would it be the plug wires or could the timing of jumped.

 

our timing is based on the crank angle sensor and i dont think it is adjustable unless you get a standalone. perhaps one of your nuts fell off and the sensor is dangling and is throwing your timing off. in anycase, which plug did you hook the timing up to?

 

C.a.s.

 

look for a plug,coil fueling or even an egr prob.

 

Mine did the same thing until i changed the spark wires.Have you changed them recently?
