In the ECM under center of dash.
The map sensor is easy to replace. It is right under the air cleaner I believe. # Remove the air cleaner. # Take out mounting screws. # Disconnect nipple hose and cable. # Reverse directions for new map sensor.
Intermittant map sensor
The MAP sensor should be on the firewall just above the brake booster.
I had this exact same problem with my Seville STS and it turned out to be a bad MAP sensor. If you are a little bit tech savy at all the MAP sensor or (Manifold Absolute Pressure) sensor is located inside your intake manifold right ontop your fuel rail. However I highly suggest that if you do not know much about cars then you should not attempt to change it out yourself. In addition do not be suprised if you or your mechanic finds that there is a large amount of gasoline in your intake manifold. This is what caused may MAP sensor to crap out. Which was ofcourse was caused by an internal fuel rail leak. The MAP sensor itself will cost you about 75-80 bucks, depending on where you go. Hope this helps, good luck!
