Like the title says, I'm throwing codes 171 & 1133. Not really sure why since I just replaced both O2 sensors, all the spark plugs and the fuel filter. I am however leaking exhaust where the headers and catback meet. If that's throwing the code great, I'm gettig the exhaust welded teusday. If it's not the leak what could it be?

If its not the exhaust leak, then it could be a bad or lazy maf sensor, but i bet getting rid of that exhaust leak will clear it right up. Cleaning your MAF with the proper cleaner wouldnt hurt anything.
 
I just found I had an extra MAF laying around. I left the car unplugged for a while, put the new MAF in and the light hasn't come back on yet. The car still idles a wee bit high, idk why, no vacuum leaks.
