My Lincoln car is doing the same, was there ever a solution?

What is your question?

The car hesitates when going above 25 mph, the temperature gage suddenly drops and the “check track” light comes up. Sometimes the engine shuts itself.

What makes this problem better or worse?

Going above 25 mph makes the problem worse

How long has your 2000 Lincoln Town Car had this problem?

Since I bought it a month ago
