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.

 

obd1 vs obd2 has no bearing on whether there is an FITV or not, preludes come with them, obd whatever

put your prelude throttle body on there, the integra one probably has different vac ports and probably doesnt match with the gasket correctly.....put the teg tps on the lude TB and bolt that on...then see if it runs right

 

Weird, because from alot of searching ppl said that obd2 engines don't have fitvs, they just have the IAC and the ecu controls the idle better and that only obd0 and obd1 engines have fitvs.
