update to code 1518
Well I fixed the IMRC problem. It was, like you all said, a broken clip. But, the IMRC is electronically controlled and is at the back of the motor, below the phlenom. It was kindof a mess to take apart and fix. But that is fixed and I currently have no codes, but the motor still runs awful. Its very rough at idle and up through the rpms
Let me give you some background info. When the motor started to suddenly run bad, the code appeared and i immediately noticed a terrible exhaust leak directly infront of the muffler. Intitally I changed the coil, plugs, and wires and then when I discovered the code, I concentrated on the IMRC and left the leak alone, but know that the IMRC is fixed and the truck still is running rough with no codes, its all I have to go on. I also just noticed that one of the catalytic converters was glowing red hot. What is this a symptom of; could this cat be revealing my existing exhaust leak or could I have a different problem altogether. In addition to the IMRC repair I also changed the PCV and check for vacuum leaks. Help!!!
