The problem has changed slightly... now the engine don't have to be warm, the servicelight comes and goes anyway.
If I drive with the light off the light comes on right after the engine hesitates for a second, if the light is on the opposite happens. If the light is off a sure way to turn it on is a sharp leftturn...
Help, where is the MAP sensor located on a Olds Cutlass Cruiser-90 with 3.3 L engine?
