the truck has 87000 miles on it and I put about 50000 of those miles on it. it has always ran like that as long as I have had it. took it to Auto Zone-no codes,engine or transmission. recently did full tune up, plus k&n air box but no dramatic change. Ford garage says "its a 6 cylinder truck, not a race car"
but for $89.95 plus tax they can put on a diagnostic tester NOT! |
