I did have a chip that I made for somebody 6 months ago start acting up
recently. It was a 2732A I think. Just out of the blue it started running
terrible and check engine light came on. Put the stock chip in and
everything was fine again. I burned a new chip for him, and it works fine.
hmmmmm.... it was programmed with the PB-10 though, not a PP. But it did use
the 'quick' programming algorithm.
