All, I just upgraded my OS last week to a 2002 (12212156) and the car has been running fine. Although this morning something really weird happened. I went to start the car up and it fired up and immediately died. So I went to start it again it fired and then the tach and speedo both shot up to 7000rpm and 150mph respectively. The car started and the tach and speedo dropped back to their off positions, and then a few seconds later they camr back on and started reading normally. So I put the car in "D" and when I gave it some gas and it nearly died and just fell on its face. It was idleing fine though. It did this a few more times, but once it warmed up it drove just fine.. Any ideas?
Car is a 1999 Camaro SS A4 226/234 112 cam TCI 3500 stall
