MAP sensor troubles
I was running through my engine stats on my FAST programmer and noticed that the KPA on the MAP does not change when the car is off or on. It reads 95 KPA at all times. Help!

Do you have any check engine codes, like a MAP sensor high voltage or anything? Does your car run bad? The MAP sensor provides input to the computer for varying ignition timing and fuel injection control. If it is reading 95 kpa, that is approximately atmospheric pressure which occurs at WOT when the vacuum in the manifold drops to almost 0. If it is at 95 all the time your MAP will be producing approx 5 volts (high) on the signal.
