113k miles.

The power train control module is is bolted to the firewall at the passenger side rear of the engine compartment.Is the PCM bad for sure? There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
it is right next to the wiper motor. as Pat said, make sure it is verified that it has failed before this expense. If it failed, the reason for the failure must be determined or you run the risk of having the new one fail as well.
