Installed Longtubes and O/r y pipe the other day & just got all my CEL cleared. (Wanted to make sure my front o2 sensors were working properly)

Went and drove/beat on the car 20 + mins and still haven't gotten a CEL. The rear o2 sensors are plugged in since one of the bungs was lost but wtf is going on

AIR is deleted also. Car seems to run a lot better now that the codes were deleted also lol :strange:

maybe your AFR isnt off by much.

some codes will put you in limp mode so clearing it would put you back to neutral.

codes may take time to show up depending on what it is.
plug in a reader and see if it "ready" mode. if not then youll need more time driving.

You'll have to drive more than 20 miles. When I replaced my Bank 1 rear O2, I had to drive for like a week (28 mi per day or more) for the ready test to finally complete.
