I have a 94 integra ls after warmed up and driven around when I come to a light or a complete stop my idle drops from 750-700 to 500-300 rpms sometimes lower feels like it wants to die but doesn’t I changed the tps since I thought that would fix it and also cleaned the throttle body still happening anyone have any suggestions I’ve heard bad throttle body’s will do this just need some suggestions out of ideas idle never goes up passed 750 Always just drops and goes up and down between those points

try cleaning out the IACV attached to the back of the intake manifold. it might be gummed up. There's a bunch of threads on it here if you search "IACV"

basically this valve is what allows the engine to idle by bypassing some air around the butterfly valve in the Throttle body.

I’ll try that out thanks and see what happens but I thought when that’s bad or clogged your idle raise high mine usually just drops
