I did some research on this site and fixed the problem. Symptons: rough idle, poor shifting, 3-2 code. Code will reset and engine run fine with cal off. All problems are with the cal on and will trigger again once cal is put back on...........Things I have done: replaced map sensor, no fix. Checked sensor passage & intake, clean. A post by Moonlighter on this forum provided the answer and I posted pics to show the fix. A little black paint to finish it off.
