wow im suprised no one has ever run into, in any case i got the code info i needed on code sc13.
did the flow chart test on the harness and tested the senser ,come to find out it was an o ring leaking
just when i thought i seen it all, in any cast 45 min worth testing and shes fixed back on track.

thats the same thing mine started to do^^^ early in the am by noon time it wasnt happy so i decided to take it home and get a better look, im thinking a loose intake boot would do the same thing.
the problem was the o -ring split on the map senser allowing air to leak by and cause the voltage of the map to go up from 1.5v to 2.0 in english it made it run rich.

You don't need a tool, a paper clip will work. The pictures in the service manual are clear enough to show what two wires need to be shorted together to enable the code display on the instrument cluster.
