First off i used to have a 92 civic cx with a B18c in high school and i LIVED on Honda-Tech.com 24/7. I got out of the import scene completely and now about 7 years later i found myself with a civic again. I just bought a 94 civic ex with a jdm b16a off a friend of mine. I have forgot about 98% of all my honda knowledge and need your help!

Heres my problem...

The car was idling at about 2000rpms when i bought it and would sometime fluctuate between 1000 and 2000rps. I bought a new TPS sensor and that took care of the fluctuating idle. However the idle was still at least 1600rpms. Today i cleaned the IAC valve which was very dirty and that brought the idle down to around 1500rpms. Iv looked for vacuume leaks the best i know how and have not found any. Also the idle adjustment screw on the throttle body is turned all the way down. Any ideas on what to do next??

Thanks!

 

try cleaning the FITV

EDIT: here's the how-to on it https://honda-tech.com/forums/acura-integra-6/%2A%2A%2A-how-%2A%2A%2A-clean-your-fitv-aka-fast-idle-thermo-valve-1564019/

 

possible also check your fuel regulator, could also cause high idle to keep giving alot of gas

 

Cleaned the hell out of the FITV. Problem solved! Thanks a lot guys!
