I have a '97 Jeep Cherokee Sport, around 187,000 miles on the odometer. Once a month or so, I will have a day where when I accelerate, the RPM’s will surge up and down, but it will feel like it is coasting, as if I do not have my foot on the pedal. There is also an audible “rattling” sound, much like a rattlesnake rattle, right under the steering wheel it seems. It will happen for about five or six seconds, and it will then go back to normal for another month.
- Side note, (This has only happened twice), I had a moment the other day where I could not accelerate for a few seconds, until an audible “popping” sound was heard on the right side of my engine, and then everything went back to normal. RPMs stayed around 2-2500 during that time.
Some have said it could be the throttle position sensor? I also think it could have something to do with my transmission, because I checked my dipstick and it is a reddish-brown color. It is very light brown and you can still make out the red, so I just assume this is just used but it is still functioning normally. No metal chips or anything.
Thank you all!
