    I recently bought a 1993 Honda civic with a h22a swap and p28 ecu not sure if its chipped. it has a check engine light because of oxygen sensor which is not on because of dc sport headers. Vtec is not kicking in, it runs fine but no vtec. Please help!

    Moved to the appropriate location.

    Is it a race header? Most headers have a spot for the O2 sensor.

    110% is still meant to use a O2 sensor "race header" doesnt mean a 4-1 or tri-y header etc , its going to have a hole with a nut in it somewhere like this that is for the sensor , if not go to the parts store and get a $0.25c O2 sensor bung and drill a hole for it after the collector and weld it on and run a sensor, the ECU needs it to make corrections on the engine , as far as the vtec goes id be checking the sensor itself and or the screen inside it , its based on oil pressure and IIRC if obd0 or obd1 it wont work if the computer is throwing certain trouble codes , aside from that Welcome To HondaSwap ! post some pictures of your ride , a eg hatch with a h22 should be ballsy
