im not sure whether sitting for so long may have messed with the maf, or the fuel regulator, or not. in my twisted way of thinking, i have a good steady idle, no exhaust problems, no bad smells or anything. as far as just driving around town, it runs fine, but i hear the "air" sucking sound more than usual. it is only on mild to extreme (which i only do for checking) accelerating that i feel the difference. just mildly pulling away from a stop seems normal, with the exception of the air sucking noise.........*sigh*
my only simmilarity to your situation is, what you said "bad gas" which i take as bad gas milage, and not old funky gas, i have, (or had) a full tank of gas
speaking of which, i got 100 miles on a half tank of gas..........ugggh

thanks for your post though, i will keep it in mind as i work thru this

Open your air cleaner box to make sure they remembered to re-install it, if they forgot, that would explain the louder suck. Also, check all the connections between the air filter box & the throttle body.

I was throwing the same codes even after replacing the intake gaskets, in my case, cleaning th sensor wires inside the MAF sensor with electronics cleaner was the solution. (Big Thanks to Jerry Lemond)

Hope any of this is of help to you.
