I looked at my map sensor last night and it has a wiring harness and a outlet that appears to be for a vacuum line, however there is no vacuum line hooked up to it, I would assume that this would be important, The car runs fine. What should I do about this?

Click to expand...

it depends if your car is speed density or mass air. if it is speed density (86-88) the vacuum line should be hooked up...if it is 89-93 (i presume you are talking about a 5.0) then it is mass air and should not have a vacuum line hooked up to it because that opening measures the barometric pressure (bap)
