Hello all,
First time posting a question here! I have a hesitation and stumble when my car is cold. I'm getting a code 31. I belive this is a code that the AFM sends out when it looses power for an instance.

A little history. I wrecked my 88T a while back and shook everything loose. My question is, would it be possibe for a loose connection on the stereo to cause the momentary lose of power in the AFM that would cause it to throw a code 31?

yes 31 is an air flow meter signal failure.
it pretty much comes down to bad afm or bad afm wiring. not sure what the stereo would have to do w/ it since it is in no way connected.
check to make sure it is plugged in firmly and inspect the wiring. if all looks ok swap out the electronics w/ a known good one. if that checks ok then you will need to do some service checks/specs on the circuit/wiring.

good luck
