I have a 91 CRX SI with a B16A, YS1 trans., Skunk 2 Intake with 460 cc injectors, stage 2 cams, header and exhaust, iridium plugs.
Runs good, no problems, BUT: Idles at 1800 to 2000 after it is driven awhile. Temp guage tells me it is at normal temp. A bit less than half way up the guage. When it is cold it idles properly. With A/C on, idles properly.
I have looked for air leaks on intake side, hoses with holes, etc.
Any advice will be appreciated.
Thanks,
Lee

 

whats it tuned on? Possible that he tuner raised the idle to have the car more street able.

 

must be running rich. lean the idle a good amount to try to make the rpm lower.
