Hi I recently bought a 96 integra ls special edition with a h22a1 swap. It is a project and when I got it it was almost finished, all that it needed that I knew was the vacuum lines figured out since half of them were plugged off or not hooked up right, along with some sensor plugs. Since the car is obd2 it has a jumper harness to obd1 running a p13 ecu. Im new to the h series I dont know much about them, but I know the prelude has alot more stuff that the integra doesnt have like egr. ect...... I finally got the car to start after replacing the coil, plugs, and plug wires. I put all the vacuum line where I though they would go but there were alot of sensors my car doesnt have that the prelude does so I did my best to figure it out. So now it starts but has a rough idle at cold start and when its warmed up it has a irradic idle and idles high around 2k rpm. if anyone else has had these problems please help i need to get my car running right since it is my daily driver any help would be appriciated thanks.

 

just so you know... H22 on a DC is almost like a dead-end. there's almost no aftermarket support and it's a nightmare to work on. you might have luck getting a hondata and tune it for your idle, or try adjusting the throttle cable.
