I bought for my son a '96 Civic EX with a '92-'95 D16Z6 engine, P2P A81 ECU and an automatic transmission. The IACV wiring was converted from a 3 wire plug to a 2 wire plug and the throttle position sensor was replaced, neither one helped. I have two problems that I’m trying to solve:
1. surging miss at 1600 RPM – just finished tune-up, plugs, wires, cap rotor and fuel filter, cleaned IACV and throttle body, replaced distributor
2. check engine light on with one code – P1509 - IACV circuit
Any possible solutions would be VERY appreciated. Thanks!
