Question about 2004 Jeep Grand Cherokee
When driving on the highway and holding my speed to a steady 50 to 55 mph, the car will start lurching, on and off, on and off, etc. The tach will jump with the lurch. It is not everytime I am doing highway driving, but will happen about 8 out of 10 times on the highway. Usually will start when I am going up a hill, but continues it on the straight stretch. I have been to 3 mechanics...nobody knows what is wrong. Help, please!! (good thing I do mostly city driving. no problem there).
If you have been to three shops,I'll assume that all the basics have been covered. Did anyone check computer stored codes? What did they see? If you are going to try to fix it yourself, you will need to get a manual and check each and every component, one by one. Also, outside of the realm of computer stuff, check converter to make sure its not partially plugged. At low rpm city driving it may be flowing just enough to get by on. Also check that fuel is clean and has no water in it.

Do yourself a favor and replace the Throttle Position Sensor.
