While I was in the dealership getting an oil change, the guy who supervises the techs in the shop was "B.S"-ing with me about how well I've maintained my old truck, what I plan on doing with the new truck, et cetera. One of the techs came running out of the shop with a look of concern. With no discretion at all, he blurted out, "That Lincoln Navigator's PCM just locked up on me, I can't get anything out of it, all that I did was plug into it." Hmm..... I wonder how that could have happened. Anybody having problems with their computers?
