I recently learned this truck has no "in-line" fuel filter. I bought the truck new and have experienced no problem until now. The truck has been showing signs of increasing sluggishness in starting, in performance traveling down the road and a significant decrease in fuel mileage. I recently had it tuned up at the dealer. It has a new air filter, oil has been changed faithfully at 3000 mile intervals. At times while accelerating it feels like it might be laboring to increase speed, and upon an initial "cold" start it idles rough and is taking a longer cranking duration to fire-up. Any thoughts? Thank you.

We find it very common for the O2 sensors
to mess up with out giving any codes
if it is something u r trying to do your self
try and disconnect the O2 sensors (you will get check engine light on )
and drive it if you notice the improvement remove and replace o2 sensor s
reset and clear code s
good luck
