Rusty sediment? You have a PLASTIC gas tank. Time to start getting worried.
Where do you get your gas from? Can you disconnect the fuel line, run the pump
a few seconds and collect what comes out to see if you have clean fuel in the
tank?
Skip a "fuel injector cleaning" for now and just run a bottle of Techron every
3K, see how that works.
