Hello, I need to know for sure if the Cat / Converter is out:frown: . I have a F150 with only 83523 miles and I have had the spark plugs, wires and fuel filter replaced. The pickup is running slow and makes a noise. Please help me:crying: .

Does the truck seem to run hotter and quieter????

No, pickup is not running hot or quieter. It has no get up and go, does make some noise maybe to the affect of something dragging or like some kind of scraping.
