My 2000 Excursion is sporadically sluggish and my fuel mileage has dropped off. Lots of black smoke when I get back on the gas after slowing down. I had the cps changed that did'nt help. The dude at ford said it might be the icp sensor, but he thinks that my f6 chip from dp tuner is causing the problems. Any thoughts as too my problem?
