Maf and O2s are not the main suspect in your case i think. Maf sensor when it bad it wil effects engine performing like too rich or too lean, rough idle, hestitation. For o2 sensor, hook up scan tool see how it switching. But again, your scan tool say particular #6 is the problem, i would look at the #6 area, vacuum leak, injector my be clogged up!good luck :cheer:

from what i learned..rotten egg smells means ur cat is working properly or could be misfiring. All those raw fuel dump into heated surfaces catalyst..chemical reactions occurs, hydrogen sulfate is the smell. Anyway you dont you start checking the basic first like sparks, could be ignition coil? Smell rotten egg in exhaust..i assume there fuel being sprayed in..catalyst converter clogged up is possible, take out O2 sensor or part of the exhaust could be a b%%Ch..test the easy things first..hope it help !! :cheer:

Well im not eric but ill reply this post:) . Make sure u replace the right belt that made noises..something people replace wrong belt. but as u said it made the squealin noise when turn on AC..it likely its the ac belt. When u turn on ac..it will engage the AC compressor clutch which is putting more load on the belt to compressing refrigerant, if belt tension is loose it will slip thus making noises or pulleys comtaminated with oil, coolants will making noises too.
1. Make sure where squeal coming from what belt
2. Check tension of all belts
3. Check pulleys for smooth clean , no oil nor coolants

That all i could think of..hope it helps
