Rewski Posted November 16, 2007 Share Posted November 16, 2007 I have a 1997 Accord LX, 2.2 liter (non-vtec...sadly). My idle surges from about 2500 rpm to 3000 rpm when the engine is cold. It surges from about 1000 rpm to 1700 rpm when we engine warms up. It also spazzes out and will stagger between 1000 rpm and about 1250 rpm. I have to shut my engine off and crank it back up to get it to stop that. I changed the IACV (idle air control valve), but that did little to stop the problem. I helped slow the rev down to where it is now, but didn't fix it. Any Ideas? Link to comment Share on other sites More sharing options...

Any Ideas? could be your Fast Idle Valve. thats what raises the RPMs when starting to get the car warmed up quicker. should be on the throttle body. check all vacuum connections too.

cranny Posted November 17, 2007 Share Posted November 17, 2007 take the cap off the FITV located under the throttle body usually , retighten the white plastic screw , they come loose and cause a vacuum leak. Link to comment Share on other sites More sharing options...
