I found that my problem was in the distributor. My original ICM/Coil may have been damaged by a set of badly fitting OEM spark plug wires. Over time the seal at the top of the spark plug tubes pushed the wires off one plug and I think this may have caused an issue with the ignition components. Both ignitor and coil were replaced with aftermarket and this helped, but the cold start issue was there. I now have a new set of good fitting OEM plugs and also just recently replaced the distributor with one from a junkyard 97 Acura CL. Car runs fine now and no cold idle issues.
