Have you tried cleaning your throtle bodies? If yes check for a cracked disconnected vaccuum hose at the intake manifold causing the idle to raise like that. Also check your accelerator pedal. Theres an electrical plug there. Might have corrosion on that. If those dont help. These things seem to have communication and learned parameter loss over time wich happens because the throtle plates were used to sit tight when new. So when they get dirty they start to sit at a different angle when they get dirty. So if you cleaned them and its still there you should look up an idle relearn procedure. I think it has to do with turning the key on and off several seconds or so. I did it on a couple of nissans. It worked like a charm!
