i have a 1990 cougar xr7 3.8. The car is stock besides an aftermarket air intake. About a month ago i was doing a constant 80kmh and the rpm's just jumped down and it was like flickering aswell as motor boggin down but then would stop and be fine. I parked it and it did it again at idle. I unplugged the fuel pump relay in the trunk and seemed to be running better. I have recently done an oil change and tranny. Filled the tank 3/4 full with 92 octane and got 200km out of it. Used to get 550-600. Any suggestions as to a problem?
 
could be coolant temp sensor

last time mine drank gas like that found out that a faulty coolant temp sensor was the problem
