Last fall before I put my car away for the winter, the car would misfire under moderate to heavy load. I changed the opti this spring, same issue. Put in a new coil, same issue. New ICM, same thing. I finally got a P1351 code so I started tracing wires. I've got good continuity between the icm and PCM on white wire, voltage on terminals a and d, and the ground is good. I've got fuel, and the spark plug wires are new. I checked continuity between the opti harness and PCM, as well as the coil connector. No fuses are blown and no wires seem broken/chafed... I'm at my wits end, what else can I do? It was running ( albeit it has a miss ) with all the new components and then decided it wouldn't start.... Any ideas? I hope I don't have to get a new PCM, I'm in the middle of paying for my wedding!

Thanks in advance,
Tim
