1994 Ford Escort 4 cyl Front Wheel Drive Manual 200k miles
I have a '94 Ford Escort. When driving down the freeway, all of a sudden the engine will start to sputter, with significant loss of power. After (usually) 10-20 seconds, it will recover, and run smoothly. It does this every 3 minutes or so; a load (such as a hill) tends to bring it on. There is no "check engine" light, or any other indication. Temps are fine.
I have replaced the plugs (correctly gapped), plug wires (replaced in brackets to keep seperated), and air filter. I also inspected the MAF sensor when I had the air filter off; it looked perfectly clean. I cleaned the battery terminals. I'm down to the fuel filter, I think.
Chilton's says I must remove the rear seat in order to de-pressurize the fuel system before fuel filter removal. I'ver tried to remove the clips holding the seat cushion down, with no luck There is obviously a trick to it I don't know.
My questions are:
Is the fuel filter the likely problem? (I have never replaced it, owned the car about 6 years now) If so, how the devil do you get the rear seat cushion out? If not, what is the likely cause? O2 sensor?
Any help would be appreciated.
have the same problem?
