Possible sticking valve. Most likely exhaust. Thsts why i said to check valve seals. Try a can of CD2. Black label for sticky vslved. Not red label. I hsve a similar chronic problem with a F 2.0 four cylinder. I know in fact sticky valves. Exhaust. CD2 will clear it up every time.

Problem only occurs at 40 to 50 mph. Otherwise just fine below 40mph
