MAP SENSOR

[SUBFAN]

THE COMPUTERSAYS THAT MY MAP SENSOR IS ACTING UP. CHECKING FOR VACUUM LEAKS, REVEALS WHAT APPEARS TO BE A PORT WITH NO CONNECTION. IT IS LOCATED ON THE TOP. ANY IDEAS??????

I think you are probably looking at the vent port for the EGR solenoid. It originally had a foam filter on it, but they usually disappear over time.
