ok i just finished a motor swap a mpfi engine into my 90 civic hatch(dpfi). but it has a power lack? and wondering why? maybe bc the egr sys is not hooked up? it is also poping up the ecu code 9( cylinder sensor) and 12 egr lift would these codes make the car run weak. could another possible cause be the throttle cable? thanks for any info
