Had an Air Dog FP-100 installed about a month ago, but I think it was too late. I keep getting codes 1688 and 1689, and it doesn't like to run much over idle if I shut it off when it's hot and come back and try to start it before it has sat for less than a couple hours (after that, it seems okay again). I'm thinking the PCM is on it's way out. Unless anyone has any other suggestions for me to try, what is the best place to get a good remanufactured VP44? I'd like to have a new PCM and all of the latest updates, but not sure if Blue Chip is worth the extra $600 over some of the other places that appear reputable? Thanks in advance for any advice!
