hey guys maybe u can help me i just got a 93 typhoon needs some work but i noticed the truck is running rich the previous owner took the cat out and when im on the throttle the truck hesitates and stumbles the only code i gettin a a 45 o2 rich i noticed that the truck runs better ig u unplug the map sensor. My fuel pressure is a staedy 45 psi just changed the plugs any ideas ??
the truck should definately run worse by unpluggin the map sensor, if it runs at all. That is the signal the ECM uses to control both fuel and timing.
As for your code 45, it is a somewhat common code but chances are with a gutted cat you are overboosting and the vehicle is detonating (even though you may not hear it, the computer is taking over the best it can)
