So finally gave up trying to solve the high idle and took it into the mechanic thinking it mght be some hidden vacuum leak I can't find. They diagnosed a bad ECM and said cost to replace was 975 plus labor. I said forget it as the car has 215K and is 17 years old. Started looking online and looks like I can get a remanufactured ecm at Carcomputer exchange for 219 plus core charge. Looks too good to be true. Anyone heard of these guys? They state the ECM comes fully preprogrammed to the specific VIN and is basically plug and play. I might just spring for it so I can hold onto the car for 6 more months. In this condition its undriveable.
