Martin Dodge Chrysler Jeep Ram

If you have the option, take it somewhere else for service. I took my Chrysler 300M here for a bucking problem when code P1299 (map sensor and Idle air control measurements not matching). This should tell you which of all the sensors in the car to test to see if they are bad. I could have worked on it myself but I figured I would save money if they used their computer and factory service manual to diagnose the problem and the PC would tell them what sensor needed to be replaced. So they swapped all my gaskets, my upper intake plenum, the egr valve, egr tube, all related gaskets, throttle body, throttle position sensor, only to find out it was the idle air control valve. Seriously? $800 in parts and $550 in labor? I feel violated and insulted. Not to mention when I got it back the check engine light was on w/ code P0123, throttle position sensor voltage. Swapped the sensor myself, all is well. If I had swapped every sensor in the entire engine bay I would have saved myself $700. how ridiculous is that? They didnt use their computer, and they didnt use their factory service manual. If they had, it would have been diagnosed on day 1. The cherry on top was they called me a liar when I said I had just swapped the PCV valve 5 days prior to bringing it in. Which I had. Why would I lie about that? what would i have to gain? It would be worth it to tow it all the way to [another dealership] in Madison, Tn both monetarily and for peace of mind. For reference, Rich, the service adviser was friendly and helpful. Bob was neither.
