In Texas we are required to have a state inspection, before being able to register a automobile. Now, my problem is my JEEP Grand Cherokee, 4.7 liter 2 wheel drive is showing the engine light on. So I have taken to a few different JEEP Shops, and still no dice...
Problem: I have replaced Throttle position sensor, I have replaced solenoid, leak detection pump, and smoked the EVAP system. So there are no leaks, and well the Firestone place said they tested it, and that it is the ECM... Now the deal wants $600.00, and Im thinking junk yard, and replacing it with a used one, SO do I need to reprogram it at that point? is the dealer the only ones that can do that? or is there perhaps something I'm missing here....? Help Please
Keep in mind the jeep runs strong, I drive it daily!
