My 04 Expedition XLT 4.6 has 220k miles and just had the catalytic converter replaced with whole exhaust system.
Drove for a bit and got a solid service engine soon light on and I got a P2195 (1/1) Pending - O2 Sensor Signal Biased/Stuck Lean - Bank 1, Sensor 1.
MAF and air filter are brand new.
Got it home and turned on to my street and she just cut out. Drifted to the curb, stopped and started her back up and drove the 50-60 yards home no problem.
Didn’t get the P2195 code prior to it failing. Did have the fuel pump recently replaced and changed out the MAF and air filter.
What should I be checking for next? Bad O2 sensor, vacuum leak, fuel injector issues?
