I was wondering, could somebody help me make sense of my freeze frame date

[My poor old tahoe]

02 tahoe it with 216,000 miles. Still factory original inside and out. No modifications except the cats were cut out, straight pipe welded in. For the most part everything still works.

Oh, a couple of glaring omissions. P0420 and p0430. Lack of efficiency bank 1 and bank 2. Oxygen monitors were listed as inc

Hey, I just wanted to thank you all for jumping in here to help an old man read the tea leaves, such as they are.

I bought my wally world scanner 9 months ago just for the he'll of it. An entire month passed before it finally dawned on me that the freeze frame remained unchanged and I would have to clear the codes to get a fresh freeze frame. Lol

So I made sure every new scan became a learning experience. The one constant over the last 8 months was, OL bank one and bank two that included some pretty crazy fuel trim numbers. That I won't bother to share with anybody here.

That is until a couple of days ago when my latest scan showed cl bank one and two. Just out of the blue my silky smooth idle & great driveabilty returned. That's what triggered my latest scan, the numbers I shared here on this thread.

So now I get to enjoy the pleasure of grinding my starter into the flywheel at least a couple of times a week because the idle is so smooth. & quiet I forget it's running. Some lady probably startled by the sound made by my starter made a smart remark as she walked by so I offed to grind off a pound for her free of charge.

so these codes are current? p0300, p0420. p0430

The 0300 could be the crank sensor starting to go.
And obviously the 0420 and 0430 are the cats.

My oxygen monitors were both listed as inc so the missing cats didn't show up as usual. 420 and 430 bank one and two lack of efficiency.. In addition 327 knock sensor and 442 small leak evap was present but didn't show up on the freeze frame

The scan is less then a week old.

You know, this all started shortly after I replaced my starter. I wonder if there's a connection

 

[Doubeleive]

Has the maf ever been replaced?

Check the connection of the crank sensor its by close to the starter. Maybe it got jostled a bit and is loose
