no problem. If the O2 sensor hasn't been replaced before, it is always a good idea to get it replaced. Usual culprit for high fuel consumption.
Vacuum leaks will cause loss of power and rough idle. I'm pretty sure the MAP sensor will give you a rough idle as well. If you can borrow a spare MAP sensor off someone, you can always swap it over and see if it makes any difference before you go out and buy one (not sure what the price is). Someone can correct me if I am wrong there.

My revs drop a little and then kick back up when I switch air con on...never had a nearly stall situation. O2 sensor can be bought from Repco or Bursons. I got mine off Ebay and haven't had issues with it. I'd stick with a BOSCH sensor...but you may be about $80 out of pocket (unless you ebay it)

i personally would never buy anything like that off eBay. it cost me 75 bucks for a oxy sensor, but thats trade price
 and the stalling could be a ISC issue, not bumping the idle up when the A/C is switched on

$75 isn't trade price, its a $5 discount. Trade price would be $55-$60.
OP when have youcleaned you're throttle body last? |

The o2 sensor is in the exhaust. It screws into the extractors(it does on my car, but I'm preety shaw it's the same) and it's easy to replace. But I don't know where the iat sensor is. Hope this helps

I guess it can be hit and miss with ebay items...but research is key. Also I'm a tight a***  .
