Saturn Repair: Accelerator, 1994 saturn sl2, muffler shop


Question
I have a 1994 Saturn SL2 with an acceleration problem.  Whenever I am traveling on the interstate the car seems to stop accelerating even though I continue to press the gas.  Any thoughts?

Answer
There's probably a hundred reason this condition is occuring in your vehicle.  However, if this vehicle has high mileage I would probably check/replace the fuel filter and test the fuel pressure.  The fuel filter is located on the driver's side framerail, infront of the firewall and behind the transmission.  It is a fairly inexpensive part that I would replace every 30k miles.  Then I would test the fuel pressure.  The test port is located on the fuel supply line between the fuel filter and the engine.  Another likely culprit: catylitic converter.  These rarely go out, but when they do your symptoms will occur.  A reputable muffler shop can run a test (exhaust backpressure)to see if your converter is working.  They shouldn't charge for this.  Without knowing more specifics for your vehicle and it's condition, I would start there.  Let me know how it goes.
