I'm only getting about 16 mpg and the pcv is buzzing. I replaced it and it was doing it again the next day. The vacuum at the intake is 22 Hg which is good. My IAC is a little loud when I do the 2500 rmp test in the vacuum (it passed and it stays steady).

I saw some stuff about cleaning out your EGR ports. Would anyone recommend that? I think I should clean the IAC screen as well.

There is also a rattle when I accelerate while driving. It sounds like it is just forward of the steering column. I can replicate it in park. I could be something loose or some kind of valve.

The air filter is new, but the fuel filter is the original.

Any advice would be appreciated

Thanks,
Tim
