    Okay, so I've been dealing with this for a while with my 2004 jeep rubicon and I think I have it figured out but I'm not sure yet. Okay the evap lines that run from the gas tank to the flow management valve are all melted because the angle I have my exhaust cut. I think that is what's causing my jeep to miss on a couple cylinders and run horrible but I'm not exactly sure if it is that or is the problem more serious? I've replaced my (camshaft sensor, coil pack, spark plugs, and map sensor) can anyone tell me if the evap lines would cause this problem ?
