306tripletfarms@gmail.com Posted Tuesday at 03:32 PM Report Share Posted Tuesday at 03:32 PM (edited) Had MIL come on checked codes with reader and said both o2 (sensor 1 bank 1 and sensor 1 back 2) rich (P2196 and P2198). I replaced them back Jan 2023 when I installed new coil packs, etc. The car is having the same symptoms when the coil packs failed,(feels like it missing at about 20-30MPH). I'm not getting any misfire error codes, what could have caused both o2s to fail at once. I cleared the codes, only driven 5-10 miles and codes didn't come back but the car still feels like its missing. Any advise would be appreciated.

enigma-2 Posted yesterday at 06:20 AM Report Share Posted yesterday at 06:20 AM Model, year, engine, mileage. Did you use OEM or aftermarket junk, etc. When you changed coils, did you replace plugs and boots? Quote Link to comment Share on other sites More sharing options...
306tripletfarms@gmail.com Posted 14 hours ago Author Report Share Posted 14 hours ago Thanks enigma-2, Sorry its a 2013, 150k miles and 3.7 engine. I used Motorcraft (and not counterfeit). Yes new plugs new sensors. I also removed the purge valve, it was leaking by. I cleaned it out and it did hold pressure, I reinstalled it and have a new one ordered. I can't recall if I replaced the purge valve when I changed the CPs. I've been out of town for a few days so its been sitting, i'll drive it again tomorrow and will follow up with what happens. Thanks again, any advise would be appreciated. Thanks Ray Quote Link to comment Share on other sites More sharing options...
