Hey scotty, I live in maine. I'm a big do it myself kind of guy. I have a 2002 toyota tundra with 130k miles on it. When I drive down the road 0-40mph truck seems to go fine. But 50-70mph it seems like I have to tac the truck out aka floor it to go anywhere. This is new aswell I drove the truck before this started happening so I know something is up. I just don't know where to start. Thanks so much any pointer would be helpful.
I'm not quite sure what "tac the truck out aka floor it " means - if it's that the engine bogs down at high speed I'd check fuel pressure and run a full diagnostic scan for codes and live data to start with, including recording data while the problem happens for later analysis.
Have you inspected the air filter?
A clogged air filter can degrade engine performance when you put a load on it.
