I just finished swapping a newer D15B7 and auto-to-5sp conversion. All went well and started up fine, but the no.1 cylinder is missing a bit. The strange thing is...no CEL at all!! I went through the usual troubleshooting. Plugs, wires,dist, MAP, fuel rail, TPS, EGR etc. Nothing is out of order. I also noticed that the engine vibrates more than usual due to the HASport EGAMH conversion mounts, but that wouldn't do it, nor would the underdrive pulleys. Any guesses? I did the whole thing myself, and I'm so close I can taste it. What could it be?
