I think a fuel filter change is in order. I would also stay away from fuel addictive and try to pump at Shell, Exxon, Mobil, BP, or any big name company instead of Sheetz and Wawa. The exception to the rule is Gitgo, I have great luck with the station half a mile from me.
I would say this car is still a virgin for Ford build quality of yesteryears. I see a lot of Fords, Chevy, and Dodge from the 80s and 90s on the road with more than 200k miles on them. The funny thing is that their odometer reset at 100k; therefore, they could have more than 300k for all we know. Quality really took a nap on America cars in the late 90s to the present. I recently took a 2009 Dodge Avenger out for business trip. It is a part of the company motor pool. While the car rode nice and has nice feel to it, it is simply no match for Japanese quality. The headliner was already sagging for a car with less than 600 miles. The engine sounds good and may last for a long time but I highly doubt it because QC is very bad with many American models now since we don't take pride in our products any more.
I love to get me a good American truck from the 70s, 80s, and early 90s knowing that it will last a very long time.
