Limp mode yet again?
got 168k on my 2011 eco that I bought new. This truck has has the chains replaced twice and the phasers once. I get a slight rattle if I let the truck sit for several days. With nearly 100k on the last repair it’s not too bad. Lately the truck has been running rough on startup, like the egr valve is stuck open. After a second or two, this issue goes away. Well, during a short trip today it felt like the truck went into limp mode several times. Even got the huffing turbo sound once. No CEL yet. Any thoughts?
