I have a 2002 Dodge Intrepid thats been at the shop for over 6 months now. They cannot diagnose the problem, this is my last ditch effort to get my car fixed. The car runs very well for about 20 minutes and when I slow to a stop it bumps hard and when accelerating after the stop RPMs jump way up and the car won't go over 25 MPH. I pull over and put it into park and restart the engine, all is fine. This happens all the time. The brain for the car has been replaced. The sensors have all been replaced. The wiring harness was pulled out and all re-done and still the same issue. The shop says the trans is fine and so it the engine but the issue isn't solved. My guys are stumped and frankly I am ready to set fire to it. Please let me know if you know how to fix this problem, I've seen hundreds of these posts of problems and no answers.
