I am using an OBD1 ECU and i have wired an obd1 external coil distributer from US SPEC H22a and an internal coil distributor from JDM H22a (the accord harness calls for an external coil, then we rewired for an internal coil). They both throw CYP. I have run the two CYP wires strait from the distributer outside the car and into the ecu, and it throws the code. I've been through 3 sensors and 2 distributors. The Sensors test ok for ohm resistance.

I am starting to believe we have a bad ECU or something mechanically is messing with the exhaust cam and causing it to lope, thus causeing an intermitent signal from the CYP, that could throw the code. Once the car warms up it throws the CYP and the RPMs start to surge.
