Idle High...2kRPM
ok, so we finally got my car to start. Problem is, it idles at freakin 2krpm!! my friend drove it up n down his shops lot, and said driving wise its ok. Any ideas to what could be causing the high idle? thanks. BTW, the car is a 95 integra w/B18CR and JRSC.
I havent had a chance to work on the car, but prolly gonna go work on it today, and will check for vacuum leaks. Thanks. I did forget to mention one thing before, the car at first start up, idles at 2krpm, after about 20 seconds, itll fluctuate rapidly from 2k to about lil below 1k and back up. Would this still be a vacuum problem?
Only happens after its partially warmed up. When the car is first started, (cold) itll idle normal. As the idle drops slowly, itll then start to fluctuate. Where is this fast idle thermo valve at? Would it throw any cel's? Thanks.
Fast idle thermo valve is the #1 suspect when the cold idle is out of spec. Since it happens to you when the engine has warmed up, focus shifts to the IACV (idle air control valve). To make sure it's the IACV you should first check your fast idle thermo and then make sure the idle adjusting screw is set properly. I've attatched the pages from the Helms manual for those procedures. If you still have the problem after doing both of these, it's most likely a bad IACV. Oh, and since this is a VTEC engine use the idle numbers that the Helms says for the B17A1. This is my '93 manual so that was the VTEC engine that year.

Wow, this is only three weeks old.
