    sounds like the ecu may be in limp mode? i would start by checking the ecu for codes, then go from there.

    Agreed with this.

    Do you know any history of the engine? i.e. has it come out of a mates car or is it fresh off the boat?
    You can have any brew you want... as long as it's a Datsun / Corolla / What is that?

    Could be this or plugs are fouling at high rpm , causing engine to miss/drop cynlinders or run in limp mode

    Sounds like limp mode. One possible cause is a map sensor fault. Check the connections to the map sensor (electrical and vac line). Simple test is to unplug map sensor and see if the engine stalls. If it stalls, map sensor is working fine.

    To check codes:
    If you have not got an engine check light on dash, use a test lamp. Find the pin on the 3rd ecu plug which corresponds to the check engine light. Connect one end of the test lamp to +ve 12V, the other to the check lamp pin.

    On the engine loom, the diagnostic connector on a zenki is near the a/c piping on the firewall. Its a little round plug with 2 pins (wire colours are blue/white(TE1) and brown (E1)). Kouki have a diagnostic box, but with more pins inside. All you need to do is bridge these two pins together (TE1 and E1) and then turn the ignition to on position. You will see the test lamp flash/check engine light flash. Have a look on club4ag website for list of error codes and what the flashes mean.
