today i attempted to adjust the wot timing(1st-2nd) via instructions with the turbo tweak chip. after i did the proper procedure the car will not idol. it started, felt like it was missing then stalled. scanmaster gave a code of 23 indication the mat sensor. i replaced same and no change.

i did not start the car prior to adjusting the timing however the last time it was driven it was fine about a week ago. anything else i should check or has anyone else had this problem. thansk for any help you can give.
