This is for Don or anyone that might be able to help. I have a 2001 225 Opti with a hot foot. It starts and idles fine. But when I make a run and let off he gas, sometimes it goes down to 1200-1250 RPMs instead of round 650. Sometimes I can hit the hotfoot a coulple of times quuickly and it will idle down but not often.I took the hot foot apart and it doesn't seem to be hanging up and I disconnected the throttle at the engine and it seemed smooth. Someone told me it might be a valve in the engine bad. Ever heard that? Any help is appreciated.
