greasyJim Posted December 8, 2005 Share Posted December 8, 2005 Hi all. The problem I'm having is a rapid 100 rpm fluctuation at idle. uhn-da-uhn-da-uhn-da-uhn-da... The weird part is that it doesn't do it all the time. Usually occurs when the engine is warmed up though, never when cold. Any ideas? oh..it's an 89 GL 4x4 wagon with the EA82 not fuel injection. Runs great other than that. Thanks! Link to comment Share on other sites More sharing options...
Subarian Posted December 8, 2005 Share Posted December 8, 2005 Sounds like EGR valve to me. You can block it off and see. Link to comment Share on other sites More sharing options...
