That code is "insufficient coolant temp for closed loop fuel control". Try removing the thermostat to see if it has stuck open. Replace it with a 195 degree.

Will the same apply to my 2000 Lincoln Town Car? I also got a code of PO125 yesterday when I took it to get a Smog Check.

Thanks very much for the advise. I will try it later on today. If the problem continues should I assume I have a bad temperature sensor?
