First thing to check is the vacuum line for the MAP sensor. Check the line for cracks, tears, and that the vacuum line is connected, of course. It comes right out of the back side of the TBI unit and then runs to the underside of the MAP sensor. Also check and make sure that the electrical connector for the MAP sensor is on and tight. |
