I bought a 92' Civic VX and the stock motor was burning oil bad so i came up on a D16Z6 for $300 with the P28 ECU. I bought a new o2 sensor from autozone (bosch universal 4-wire o2 sensor) and rewired it, it has no check engine light now. Well my real question, is there anything else i need to wire? I'm running the full Z6 motor, head, and intake manifold. I had to use an IACV from an accord i think... it matched up so i went with it. I also had to take the TPS off of the Z1 and put it on the Z6 since the Z6 didn't come with one. I also took the oil cooler off the Z1 and worked it into the Z6. i'm running the Z1 tranny. and everything else that's bolted to the engine compartment/fire wall is from the Z1... the motor runs a little funny... it ildes irraticly from like 600 to 1000 and back and forth from there, when the idle goes from 600 to 1000 it has a sort of putt. another problem is MPG i topped off my tank and drove 130 miles and it went down a half tank. any information, advice, or comments would help out a lot. thanks.
