i swapped a jdm zc into my 1997 Honda civic ex i am using a Honda civic dx wiring harness for the angine the car starts right up and idles well ( accept for i have no iacv) now when i give it gas the car just dies but if i tap the throttle i can get it to rev i have 3 codes iacv secondary 02 sensor heater and vtec malfunction i dont care much about the idle i just want the car to be able to drive the dx harness has 2 o2 sensor plugs on the harness where my ex engine has one under the car and one up front

 

Inspect your cap and rotor for corrosion.

 

The iacv will keep your car from running right, i would replace the iacv first and then move on to the next step.

 

any other ideas

 

Now when you give it gas are u flooring it or in netural or do u mean when u are driving and give it gas that it dies or bogs out. Could be your fuel rail, check ur fuel pressure shouldnbe at or around 40psi

To many major CEL's, faulty sensors/Cel's can make your car do crazy ****, I've seen a simple broken TPS sensor not let a buddy's car rev past 2500 rpms. Re-check your wiring and sensors.

If I remember doesn't the zc use a one wire 02 sensor? Are you using those o2's still? If so you need to put the 4 wire o2's onto your zc off of your ex, get an IACV asap, and as far as the vtec malfunction it sounds like you didn't wire up the extra sensors for it (vtec solenoid & knock) .. http://technet.ff-squad.com/ has all the info to accomplish that.

 

its a dc motor dx harness ex ecu

 

put some gas in it
