Why would a 2002 Ford F150 run loud?
My dad owns the truck but I drive it frequently. A few months ago we noticed a knocking sound and there were issues with accelerating once you hit 50 mph. After having it looked at the mechanic temporarily fixed the issue. We still don't go more than 55 mph and never use the freeway.
Anyway. To me (at times) it seems as if the truck runs louder than it should. On start up it's a really loud roar and whilst driving it sounds as loud as an 18-wheeler. I don't drive it until it's warmed up so I don't think it's a cold engine then again, as you may tell, I don't have much knowledge on trucks/cars. Any help or theories is greatly appreciated.
Assuming we have a turbo? Check pipework and exhaust system. Sounds as though we have a split.thus as boost is generated and escapes it causes roar noise or a loud hiss.
as we go up speed range the lack of pressure fails to boost engine hence lack of power and acceleration. What did mechanic fix?
having a fault code run would be helpful as would taking a peek under bonnet and rev engine to midpoint look, listen see if any gas escape etc.
