pull the air cleaner and run it open to see if the stumble went away.
This way, you changed the limp mode that run rich to cool and ignition to retard.
I am going to mustankmodder a video they removed from my air space is they think i am messing around.
Bet me i cannot match that passion you have for that car is the same blood stream.
It is too complex to tell you about that cel flashing on the dash ing through the snow.
I think you are being snowed unless you can show me those 5 wire plants and who is reading 3 signals at what grid position at the wire harness.
So, are we down to 2 wires if:
1. Is ground?
2. Is hot to the unit?
3. To the o2 side is now at the main plug in side of the main harness?
Where does 4 and 5 wire go is, "back probe it" and you hurt no harness integrity is do not cut the harness is.

all wires are good...put in new fuel injector on #6 and still no change.it fouled the plug in minutes after starting the car up....
what else could it be?

What brand of fuel injector did you use, aftermarket? If you don't use the same as what the other ones are (GM), it can cause problems. There can be a slight difference in fuel delivery between an aftermarket injector and the rest. Then the oxy sensor(s) will be reading either a rich or lean condition and your computer will try to compensate for that one injector and mess up the whole system. I've been there. If you put in a non-GM injector, take it back out, soak the old one in carb cleaner for a while, and put that one back in. You do not want to mix & match injectors.

I tend to agree with Gorn. Check for a stuck or held open injector for cylinder #6 (make sure the wire from the injector to the PCM is not shorted to ground), or for the spark plug wire shorting or arching to ground.

where could i do that or how...? just check to see if the wires are touching anything that they shouldn't be? and how will i know if the plug wire is arching to ground? i put a new plug wire on that one (#6) and still no change....
