#1 of 8 Help with Map sensor
May 31, 2009 (7:23 am)
Had black smoke issue changed out the fuel reg sensor fixed that problem,but it still is running real rough . When the vacuum from the map sensor is unplugged it runs better when I plug up the map sensor it backfire through the intake and runs horriable. I checked the map with a meter there is more volts going out than what it says there should be.Anyone got any ideas?

The manifold absolute pressure (MAP) sensor can certainly affect fuel delivery and give the symptoms you describe. Perhaps someone with hands on experience will jump in and offer some guidance. Anyone?
