I have a 2002 Dodge Intrepid with 165000 miles on it. Lately the check engine light has come on and stayed on. After driving it for about 20 minutes at a speed of 45 or higher, when I slow down below 30mph the engine gives a bit of "jolt" and I can no longer accelerate over 35-45 miles per hour without the engine's RPM's revving well over what they should. It's almost as if it gets stuck in a lower gear and won't switch gears after that. If I turn the car off and restart it, it goes back to normal until I again have to slow down to under 30mph. Any suggestions as to what this may be?
