Good day po! my ride is a 03 toyota grandia with 3liter 5L engine. problem ko po, yung idle up nya. from cold start, rpm is about 800. when a/c is on, about 900. but after several minutes of driving, pag stop ko, idling, nagiging 1000 or more ang rpm. and when a/c is off, around 900 na. tama po ba yan? diba dapat pag stop and a/c off dapat balik sya sa 800? how much pala ang tamang rpm sa idle with and w/out a/c? thank you
