Atmospheric Pressure Sensor Question-Need Help
I have a 1987 F-150 4.9 6 cyl. 4x4 4spd that I just purchased. It idled rough and while inspecting the vacuum lines i found the line coming from the BMAP sensor that was not hooked up. When I hooked this line up while the engine was running it cleared up for a second then got a lot worse than before. Also with the line off it seems as if the truck is running very rich, pouring black soot out the exhaust. Any help with this problem will be much appreciated
