It looks like you may have smoked your pre-cat.Got the scanner in the mail yesterday but I didn't get home from work until after dark. Here's what I got for codes
I completely forgot to share this info, but omw home from work yesterday it drove fine to the nearest gas station at 7/8ths of a tank but I still stopped to fill er up... Within 2 miles down the interstate from the station it started doing it again with a completely full tank and continued doing it for the remaining 12 mile drive home. Once I got off the highway it did it again on the takeoff from the exit ramp for roughly 3 seconds and once it cleared the cel started flashing. When I started it this morning it wasn't flashing, does it throw a different code than what's pictured to make it flash?It looks like you may have smoked your pre-cat.
But maybe not.
Clear the codes and see if they come back.
Fuel trim is something worth monitoring when looking for fuel/air problems.
Keep your tank topped up until you get your parts replaced.

<Your car is really sick right now.
Is there any way you can stop driving your car until after your fuel pump and filter are replaced?
Yeah, I'm not gonna drive it until I change the plugs, wires, coils, fuel pump/filter and the crankshaft sensor
I'm not sure, but if this means short and long term fuel trim, it doesn't look right.
It may be proof that it's in limp mode?
0.0% and -100.8%.
I'm in Ohio and I ordered a new O2 sensor also, all of my parts will be here by the weekend. I should get everything by Friday so by Saturday everything should be done... I'll follow up as soon as I get it done!Coils and plugs for sure. You could try removing and cleaning the 02 sensor wiping it off with tb cleaner or rubbing alcohol and see if the 421 code goes away. The non fouler is great as long as you don't live in CA they frown on those here. But theyre cheap and easy to install and work 99% the time. And reset the ecu after so you do the fixes.
