Now that I have near 60k miles my mileage has dropped to high teens to 21 MPG. I clean the MAP sensor every 6k. Any suggestions? |

I know it's hard to notice gradual decreases in power but is your power output like it was when new? Also how does your MAP look every 6k |

The map is a little gunked up each time I clean it and I change the air filter probably more than I need to. I get free oil changes from the dealer so I have been using the same 0-40 from the dealer. I wonder if the MAP sensor could be going bad but not bad enough to throw any codes? I was getting 20 to 24 mpgeven towing the boat now I get around 20 when I am not towing and drop into 15 to 17 towing. The boat isn't all that heavy eithor, Fisher Marsh Hawk 165 aluminum deep V with a 50 merc. |
