So my cel just came on today, its a 99 Si, and the sites I've seen only show the codes of a civic up to 98... I read mine the old fashioned way, by jumping the 2 pronged connector by the ecu. I got a code 14 (IACV). I just recently replaced my throttle body with a p73 type r one (bored out). Could the throttle body be doing this? What should I do first? Oh, the car is revving itself, sometimes cuts out at low rpms, those are the only symptoms so far).
