found the problem after taking everything apart 3 times. asked a gm tech. and he told me its was either a bad ignition coil or module to change module and clear code. come to find out the part store sold me the wrong module to begin with. so from now on I will look part numbers up online and order do a in store pickup

Unfortunately this happens often with sales people that do not have enough experience with cars.
I always look up the part #'s before going to the store just to be sure and to save a trip back to get the correct part while you are in the middle of the job.

I sure miss the old school auto parts stores, those old guys behind the counter sure knew their stuff..
