idle speed

My 1998 civic has been standing for about a year , now when it comes up to temperature the idle speed varies from about 1,000 to 2,000 rpm any ideas please

Re: idle speed

Is it pulsing (gradual increase, sudden drop), or hunting (gradual increase and decrease)? Is the CEL on?

Remove, clean, and re-install your IACV, and check for vacuum leaks.

Re: idle speed

Yep, clean IACV check all the lines that run from the engine to IACV. Also check the throttle body gasket for leaks. Thats where mine was when I had this problem.
