    99 Mustang Gt Instrument cluster and pcm

    What's the best way to clear codes in the instrument cluster? Trying to figure out a pats issue. Found out the pcm in the car was not communicating with obd2 so I swapped a donor pcm and instrument cluster that came with the car in. Was told the cluster and pcm were out of the same car by...

    PCM change for tranny swap? '94 V6

    Hi all! Long time stalker, first-time poster. I am going to be putting my 94 V6 under the knife and converting the blown AODE to a T5. My question is do I need to have the PCM reprogramed/ swapped completely to accommodate the manual? If so, any thoughts about FS1... I've heard good things.

    Engine That Is Soo Her...

    I have made previous postings about my car (1994 cobra with X303 Ford Racing Engine), but nothing has really come out of it. I think the problem back then was CEL codes. As many problems I have had with this car (very strong gas smell failing emissions) the car would not pull any CEL codes. Well...
