I have a 2000 3.2TL. Have had several instances were the Engine Check Light comes on . The first time I was driving to Fla, and it stayed on for 3 days befpre going out on its own. Dealer in Fla said there was no trouble as it had gone out, and couldn't check for fault as I had started the car more than 20 times. It comes on now when a sudden busrt of power is applied and usually goes out after a few days, but this time it has stayed on. Local dealer says its an Oxygen sensor problem. Cleaning the sensor is only a partial fix. Has anyone else had this problem? Would appreciate inputs.
