My 06 Freestar with 127,000 miles has been running like a champ. It's been dead nuts reliable, never missing a beat. The only issues I've ever had was a bad wiper switch and brake light switch that would turn the brake lights on when it got cold over night.
The other night coming back from PA, I felt a little hiccup from the engine and thought it was odd. Yesterday I noticed it feels like it's misfiring at times while accelerating and cruising. The check engine light never came on and still is off which I'm thinking might be an injector that's clogged or dirty. I would thing if it was a spark issue, the raw fuel in the exhaust would trip the O2 sensor. I was also thinking maybe the EGR valve.
I think first I will replace the 127,000 spark plugs as a good start
