Hello. My 2000 Silverado(4.8L, 1500 ext cab, 4x4, Manual) sometimes has idle problems. Sometimes when I shift gears the ilde goes high(2500 to 3000 rpm), also when I tap the throttle in neutral. I have a code reader and it says no codes. No check engine light, either. At other times it runs fine. One more thing, sometimes it is hard to start after I've driven for awhile, then stop somewhere. It recently passed emissions inspection, no problem. Thanks for your help.J.P.

I checked it with my code reader. I manually played with the throttle at the T.B.
