Yeah I agree it does not sound like a sensor. I put a screwdriver between my ear and the injectors and I can hear them working. Plus they were working fine before the clutch. I just got back from changing my wires and no dice. I still get a CEL on and off. While the CEL is on, I pulled over (by the way I just leave the code reader plugged in and my hood popped all the time) and I ran the code reader WHILE THE CEL WAS ON and I get systems pass. I think I'm getting a random misfire under load. That's why by the time I pull over, idle, and run the KOER test it's running fine. I'm gonna go out when its pitch black, run it and see if I am jumping to ground somewhere. Somethins got me hopin this is ignition related.
