How do I fix this?

I do but need to find a good post or help from the community on what to look for. My scanner has both freeze frame and live data. It’s an Ancel AD410 specifically.

You're looking primarily at fuel trims (both long and short term) and O2 (B1s1, B2s1) data for this.

Most likely not the O2, since you have both banks, but check them anyways to make sure they're switching properly.

With your codes you've likely got either:

1. A vacuum leak somewhere that affects both banks. @SnowDrifter has listed a bunch of spots to check. I would add the injector o-rings to his list.

2. A fuel delivery problem. Pump, filter (if you've got one. Not sure what year you have), or injector(s).

3. A goofball flex sensor if you have one
(VIN Z)

We can figure out which one to be looking for based on the fuel trim live data. With both 171&174, your long terms are going to be maxed at 25. Look at your shirt terms at idle when warm and in closed loop. Watch what they do when you get on the throttle. Are they going up or going negative?
