I have a '06 5.7l Commander. I just changed my belt tensioner (took much longer than I would have liked ). I went to drive it, feeling great about my accomplishment at saving a couple bills, and the ETC (electronic Throttle Control) started flashing and the ESP (Electronic Stability Program) came on solid. I had NO, I mean NO, power on the gas pedal! I limped back into my garage and didn't see anything specific. My Jeep had NO problems beforehand. The belt is on right and the tensioner seems to be working fine. I did remove the A/C coolant hose from the radiator and that spilled a bit, but I wouldn't think that could have damaged anything. Anyone have any ideas? Thanks!
