heres the deal,1994 integra LS,stock b18b1,auto trans. when i first start the car it idles at 1900rpm,when it warms up it idles at 1300.. ive checked.cleaned the following iacv-cleaned fitv-cleaned vacuum hoses-checked ignition timing-checked/set cam timing-checked/set fuel pressure regulator-replaced firing order-checked throttle body replaced with a good one(tps,map,etc.) everything is fine and within spec..i have to do a timing belt and valve adjustment because some valves are loose..but that shouldnt cause it rev high,would it?? car has a cel for a transmission sensor but i doubt thats causing high idle.. if i rev it up when warm it revs fine,idle will drop to 1100 then bounce right back up to 1300 and hold steady. what else could i check?
