  1. drolds1,

    Do you know where is the Mass Air Flow sensor located on the 3.0L engine? I'm thinking of spraying some CRC valve cleaner into the engine but after the MAF?

      The MAF is located in the intake tract, as on all cars.  This is an example (not your engine). Himage.png.f32fb16b4b55750d28924c42ae9fb11e.png

       

      However, as we've cautioned several times in the past, DO NOT spray any kind of cleaners or solvents into a Ford turbocharged engine.  There is no FoMoCo-approved method of cleaning deposits from the intake valves other than replacing the heads.  Should a chunk of carbon come loose as a result of the cleaner and get into a turbo, it will result in an expensive repair that won't be covered under your 6/70 powertrain warranty.  Even if that scenario doesn't occur, the relatively cold solution hitting the very hot turbo blades could result in thermal shock. IOW, stop thinking about spraying anything into your intake tract on this engine.
