Default car wont idle after hooking pcm back up
so i unhooked my pcm and tried one from another car to see if the tune would work. it would so i rehooked mine up and now the car wont idle. If i keep my foot on the gas it will stay alive, otherwise it just dies

Keep trying, it should relearn and run better within 10 -15 minutes.

It may be that the position of the idle air control valve changed between PCM swaps and your PCM has no way of knowing this. Search for the procedure for resetting your IAC, that way both the actual position of the IAC and what the PCM thinks it is are the same.

I'd try resetting the PCM and see what happens. No codes right?
