95 GTS code help and ideas....Please

ok car set while I was deployed. came home and getting bad bog and low miss/rough idle. Code 157 replaced MAF. Code 189 pops up. swapped the two O2 sensors and now my autometer air/fuel meter isnt working. So I am guessing that the (left) drivers side o2 was no bueno. was too late on sunday to get to parts store. I am going to replace both o2 tomorrow, but both were new Bosch only about 2 years old, and only 1 years worth of use. I also replaced plugs, were Double Platinum Autolites, went with Platinum autolites AP26 I sprayed the hell out of the engine bay with starter fluid no Vac leaks to be found. Whiskey Tango Foxtrot! I have reset the DTC codes everytime I made a change, and done the KOEO test a friggin million times, why wasnt the 02 codes showing before I replaced the MAF? did the MAF trash the 02 sensors? Any ideas? Thanks Baffled here. When I left AUG1 last year no problems, wife started and let it idle once a week while I was gone. Could that have crashed the sensors? Thanks again oh great gurus of all things Stang!

Starting it up and just letting it idle probably didn't get the O2 sensors or catalytic convertors hot enough to do their job properly. You might need to just take it for a long drive to clear it up if possible. I'd also put some fresh fuel in it.

Bad gas in gas tank. Burns funny causing it to run bad and throw fuel to air ratio off. Run premium for a couple fill ups with fuel system cleaner

+1
If you run the premium then switch back to a lower grade, you will have to remember to allow your computer time to relearn. From my experiences with my 86 GT, this can take 20-30 miles of driving under various loads.
