I have an lmm and i was just changing my old glowshift gauges to isspro factory matched gauges. The glowshift gauges i have just spliced into the factory fuel rail wire orange/black and yellow. Everything was fine. now with the new gauge wired in the same i get a power reduced message in the dic my no codes my autocal can pick up. un plugged that gauge and truck runs fine. Then i was checking my connections and accidentally ending up starting the truck with the rail sensor unplugged. Now regardless of the gauge in or out i have a rough smokey idle sounds like its surging kind of. Took it for a little drive and the desired rail press and the actual on my auto cal were way out to lunch. Does anyone have anywhere to start looking?
