The harness in that area around the AC compressor is susceptible to corrosion at the splice points. Clean it up with some brake cleaner, and carefully, with the engine running wiggle it around with your hand and see if you can get the engine to stall or miss. Or, you might just need a new crankshaft position sensor. The Grey and Dark Blue wires off the crank position sensor just go straight up to the PCM plug (pins 30 & 41 middle plug).
