That was really hard to read and your car doesn't have a carb.

It sounds like your firing order is messed up, make sure your spark plug wires are where they are supposed to be.

ok carb = throttle body and i pulled the timming cover and it didnt skip a tooth any more help

look at the map of maf sensor

Steve, did you make sure the firing order is correct?

Has nothing to do with the timing belt.
