No don't replace it agian. I am almost positive that there is a new PCM calibration for this car. I know that there is one for code P1404 just not sure what years but I would almost guarantee that is what you need.

thanks toadster25,


and your right, there was a new pcm recalibration for my 2001 buick, I took to dealer and they recalibrated it and now its good.


regards
