2003 Lincoln Town Car Executive - idling issues.

[qualified-merc]

Through a long strange series of events, I just purchased a 2003 Lincoln Town Car Executive. The car has some minor issues, nothing out of the normal though. About a week ago, the car died several times when idling or at a red light. so, I cleaned the MAP sensor and used Amsoil power foam to clean the throttle bottle. For about a week the car has run well except today it started acting up again. The engine began acting like it wanted to die/ran rough at idle.

So this morning, I added a half bottle of Gum-Out to the fuel when I filled the car up with 87 octane gas. I'm wondering if I should switch to ethanol free gasoline?? Or, could there be water in the gas??


BTW, I purchased this car so I could get down to business and finally fix the 1984 300D correctly which will take some time. Having the Lincoln will allow me to repair the 300D correctly which is priceless in my opinion.
