I have a P1092 - but the car runs great. This weekend I did plugs, primary O2 and cleaned the MAF, but the code came back. My bank1 LTtrim runs about 7% and bank 2 runs between 7.8 and 8.5%. the ST trims bounce around while driving from +12 to -20. An indy shop did a smoke test, found no problem but said I need a new MAF. My CCV is still original (109K) but it doesn't seem to have excessive vacuum at the cap. Would like to hold off on CCV replacement till spring.
