My car has been running really lean for the past few days, so as I was pulling data from the computer I noticed my map sensor is reading a 9-10mmHg. Now shouldn't this be reading exactly what I see on my boost/vacuum gauge? I'm seeing 22mmHg on the gauge.
I'm thinking vacuum leak, but I'm not sure.
If your boost gauge is accurate, and reading from same place as the map sensor, then yes.
