i am new to the site i have owned many hondas but never had any major issues
i recently baugt a 1996 honda civic ek hatch back
it has a d16z6 vtec with a non chipped p28 ecu with jumper harness out of a 1994 civic si eg hatch
it was a quick swap very sloppy somethings arent plugged in such as the iacv and the purge valve
it runs fine but if i hold throttle to 1500 rpm the idle with not stay at 1500 rpm it starts to rev

so my issue is at 1500 rpm it bounces from 1500 to 2000 rpm very hard to drive this way i have to rev the car to 2000 + rpm just to take off
idk if this has anything to do with the iacv and purge not being plugged in but ive always unplugged iacvs and purges without issue

it does this when cold and warmed up with and without any loads on the motor

car is basic no air conditioning no powersteering
