Got a question, I've been having some slight idle problems since I got my h22 working in my integra, and think I might have finally figured it out perhaps. I just learned that obd2 engines don't have fitv's but obd1 engines do. Well back when I did my swap I used my b18b1 LS throttle body because the tps was broken on my prelude one and it had the same bore. Anyways, it was from a 96 b18b which is obd2 and the engine I'm using is a 93 obd1 h22a. So wouldn't that mean that the throttle body from the b18 I put on wouldn't have the fitv? I just went out and compared the 2 and I can't see any physical difference without taking it apart, is there a sure way to tell? Thanks.
