7.3 Bad #8 Injector
sooo... my 2000 F250 was down to getting about 6 MPG. I took it to the dealer and then ran it through the "tests". They told me #8 injector was bad and they replaced it. Heres my question.. will 1 bad injector cause a drop in fuel economy of 70 percent or more? SHould I believe they have found the problem or dig deeper?
Thanks ahead of time!

OK... back from the dealer and here is what the work order says: "PERFORM POWER BALANCE TEST CYLINDER 8 LOW PERFORM MANUAL COMPRESSION TEST 390 PSI REMOVE AND REPLACE #8 INJECTOR ROAD TEST OK"
Other than a bit smoother idle, I cant really tell a difference. I filled her upo to the top, added 16 ounces of Power Service Cetane booster and will run it to find the MPG now.
BTW, I have a Bank's tuner chip in it now... im getting the vibe I should rip it out and go DP... any feedback?

Thanks for all the replies!! But here is the million dollar question... if I cant rely on th dealer for a proper diagnostic or repair then whom can I turn to?
As I posted earlier, I just purchased this 2000 F250 with 142k miles on the PSD. The truck was taken care of and seems Ultra Clean in terms of the interior, paint, etc.
We are getting ready to go on a family vacation that will entail 3500 miles of mixed driving in CA, NV, AZ,UT, WY, SD, NM all the while towing 26' and 8500 pounds of travel trailer.
I know we cant always plan for everything, but the last thing I want it to have this truck take a crap on me in the middle of nowhere.
So bottom line... where do I go thave this tuck ran through a COMPETENT diagnostic?
Oh yeah, 1 other thing... does anyone recommend I pull an oil sample and send it in for analysis? and if I do, how many miles should be on the oil before doing so?
Thanks!!!!!!
