Hey Vic, you were right, the purge fuel tank hose was disconnected. Once I plugged that one back in the idle was much better, unfortunately the hesitation at 3500 with the foot down was still there and also the stumbles at lower revs ~1500.

I bought some MAF cleaner and gave that a shot but didn't do much so maybe the MAF is too far gone. Will probably have to bite the bullet and just get another one... *sigh*. Where's the cheapest place?
