i just installed a d16z6 in my hatch and the motor is sputtering at partial throttle and bogging at wide open throttle? it was working fine when it came out of the other car. what causes this?

 

Are there any check engine lights..

 

sounds like something is unplugged, how does it idle?

 

its throwing 2 codes o2 sensor and map sensor.

 

Could also be spark plugs. I've had some pretty bad sputtering when my sparks plugs needed changing.

 

Fix both of the check engine codes. the o2 sensor if it is bad will f up your entire fuel curve that could make things sputter if is going rich or even lean. and the map sensor will usually make your car run like **** if its bad.. So try to fix that stuff first

Yes. Sounds like a problem with the MAP sensor or its wiring somewhere.

 

fixed the map sensor but i'm lookin for the wiring diagram to use the 4 wire oxygen sensor since my car car came with a 1 wire o2 sensor. i'll check my plugs tomorrow also since its dark now
