    I bought a 89 civic with a 90 ls swap
    cant figure out whats wrong with it
    :confused:

    It backfires and runs like ass. wont rev past 3000 er so
    almost like the ecu is in limp mode but i tried a new ecu any suggestions?
    also changed spark plugs and wires cap and coil ive checked the timing and it seems okay

    alright thats what i was thinking too
    maybe ill try a crank sensor too i did some reading and it said that would make it rev bounce and limp mode

    also cleaning the iac could be clogged and the 02 sensor

    all of these are integrated onto the distributor. the entire casing has te be replaced in order to change the sensors. if you change the dizzy to a known-good one, it will probably fix your problem...
