At 38,000 miles I had my fuel rail pressure switch replaced due to leaking. Now at 42,000 miles I am aveaging 19.7 MPG instead of the 21.3 I was getting. Could the new switch have caused this?

Does seem like a coincidence. Keep checking your mileage. This time of year fuel can be funny.

At 45,000 miles I am still only getting 19.7 MPG. Is it possible that the computer might need reprogramming to go with the new fuel pressure sensor? Also my towing mileage has dropped from 10.5-11 MPG to 9.5-10 MPG


Eric or any of the other Techs know anything about this?


Sure would like to have an opinion on this before approaching the dealer.

I can't believe one of the Tech's doesn't have an answer to this problem.


Please respond !!
