I am also havine an idle problem with my 92 egt. When you first start it up in the morning or after it has been sitting there for a while it will stay at like 2500 RPM´s then after a while it will go to like 1500 RPM´s and it will stay there for a long time before it finally idles and it idles at 1000 RPM´s. I checked the hose that comes off of the VAF and no cracks i could see, i checked my PVC valve thinking that might have something to do with it but no luck. Anyone ever have this problem and can anyone help? Thanks :-]
