Engine Running Cool
The engine in my 1996 Windstar 3.8 is running cool. I drive 30 miles to work one way, and by the time I get there the temp gage barely moves. I know the engine is runnning cool because it runs rougher when this happens. If I drive through slower traffic for awhile it will reach more towards normal operating range. I have already replaced the thermostat thinking it was stuck open but no luck... any ideas???

Re: Engine Running Cool
Can you get hot air through the HVAC? Perhaps the engine is warm but the temp sender or gauge is giving a bad reading. I am not sure if the same sender is used for the PCM and the gauge but if the PCM "thinks" it is cold it will adjust the air/fuel ratio to compensate which will affect performance. If it is the same sender as the gauge then of course the reading will be in error as well.

Re: Re: Engine Running Cool
i do get hot air out of the HVAC. Your suggestion of the sender to the PCM makes sense. I will look in to it. Thanks alot.
