I have an automatic '99 Cougar 2.5L V6 and it has about 111000 miles on it and i'm glad its gone this far. But a couple days ago it started something really freaky. I will be just driving down the road and after about 5 or 10 min of driving, the RPM's will drop just a little bit, but the car will maintain speed, and then they will jump way up like its about to just take off on its own. And i'm not even pushing the pedal harder or anything. Then, I guess it realizes that i'm not giving it enough gas to go faster and it will drop back down to normal RPM's. And then it goes back and forth. I'm afraid that it will do a number on the gears, reving up and down like that when i'm driving so I'm trying to only drive it when I need to. Someone said that it could be the fuel filter, but its getting enough gas. It just thinks that its getting more than it really is i guess. Is there some kinda of fuel sensor that may be screwed up or is it about to die on me????
