Today, while towing my CJ7, my truck misfired twice. Complety seperate occasions on my trip. The second time the check engine light came on. P2149 is my code. I believe that it means a misfire on cylinders 4-6. I have rececently been loosing mileage significantly. I had the IAT sensor replaced, and I had a BG flush of my fuel system. My fuel system came up very dirty. After the second misfire I put the Edge J/A on Stock. I did not have any more problems. I did not know what the code was, so I did not drive it very hard at all. First time I have been passed!:mad: Should I call Edge, would this be a problem with the chip? I checked my injector harness connections, they seem to be good. Give me a direction to attack this one. I need to haul my Jeep to a parade for the 4th. Thanks! Truck info in the sig.
