Grand Marquis 8-cyl

  • 62,800 miles


On 6/1/14 I was driving South on SR44 in Ohio near lake punderson and following a farmer driving a farm tractor.when I got a chance to pass him I accelerated to kick in the passing gear and when I cleared him and left off the throttle it did not respond instead it continued at a high speed for a few seconds before letting off.I thought maybe the throttle got caught on my car mat. I very rarely push the throttle to the floor. Then yesterday 8/20/14 I was with my family traveling North on I-77 in akron Ohio and again I kicked the car into passing gear to pass and this time it accelerated and did not retract on my letting off. I slid the shifter into neutral and placed my foot under the pedal and lifted up and it came up but I thought I felt some resistance with the peddle.I continued on to my destination only a few miles to copley Ohio.I parked the car turning off the engine and slid the seat back and on my knees in the driveway I reached in with my right hand and pushed the peddle all the way in and let go of it and to my surprise it remained in the full throttle position. I then pulled the throttle back and felt resistance. I pushed it back in again and it stuck but came back with less resistance so I pumped it back and forth and got rid of the sticking problem.I then thought it may of developed some light rust on the linkage so I looked up under the dash and there is no place to lubricate that's when I realized I really had a problem and possibly a lot of people owning a similar car.as of this writing I went out to the car in the garage and reached in and pushed the throttle to the floor and it came back nicely.a lot of people will not react as I did and shift into neutral.
