Does my truck have a knock sensor and egr valve?Where? My truck has 59,000 miles on it and has started to "ping" under loads or going up an incline/fuel economy averages about 8 to 9 mpg in city and 12 hwy, is that normal for this truck model?

Do you
have the same problem?

Yes I would venture to say they do have. I would have the timing checked on the truck. The pinging can cause damage to the engine. Octanes are important to the running of engines and the way they perform. Your mileage is pathetic. I know 18 wheelers that get that mileage or better. I have a diesel Excursion that pulls a 6 ton load and gets around 15 mpg.

Was this
