    Ok so i put a 1998 acura integra ls B18a1 in my 1991 civic Ex 4door. the swap was painless, and the wiring seamed pritty easy.

    The problems i'm haveing are when I start the car it is throwing a map sensor code "CODE 3" on my pr4 OBD 0 ecu its also throwing "CODE 7" Throttle angle sensor.

    The car will start but when it is running its rough, and when i hit the throttle is will rev up , and sound ok. the seconds after i let off the gas the car will die. I start it, and it starts. same codes, and same problem. I have the 3 wire map, and tps hooked up, and the plugs are the same. I tried to switch them it really did nothing..

    I want to know if anyone can tell me how they fixed this, or if anyone has the wire pinouts for the tps,map sesor? thanks

    thats what i thought, but I don't know what to test cos I can't find a wiring diagram for the tps, or the map. The harnesses have differn't colored wires then at the ecu. So i dont know what wire goes to the ecu for signal form the tps. Cos the ecu scamatic only has 1 tps going to the ecu.
    I was thinking is their a power,ground, signal?
