Question about 1988 Toyota Cressida
Clean the IAC (idle air controle) located at the throttle body with brake clean, remove the intake duct, there is a cut out that allows air to pass to mix with the fuel inside the trottle body (about an inch or two beyond the lip), it's either stuck (most cases) or gone bad, if you disconnect the electrical plug it should stop the erratic idle, but you have to plug it back in. I spay wd-40 in the same orfice to lubercate the IAC
