Can someone tell me where I can find the PCM on my 92 F150? Fighting a high idle problem. IAC is OK, so is vacuum, must be PCM??

 

Hey Red92. You'll find your PCM located right above the passenger side kick panel. Something like a 6" x 9" aluminum looking box. You can come on down to our "lower crusty" section, in the basement level for pre 97' Trucks. You can ask questions or use the search mode for previous topics concerning idle and cleaning the throttle bore & the IAC valve. Could also be the Map sensor and the TPS. Welcome! Les
