What's weird is at idle your long terms are lean, and on cruise they creep up slightly. I'd still look for a slight vacuum leak. Inspect every hose after MAF sensor that feeds into the intake manifold.
Still in the learning process of all of this, so which abbreviations am I suppose to look for when I rev it? And what numbers should they be at at idle and then while revving? I could also try to record a short youtube clip of idling, the rev and then a take off to cruising speeds

Could you possibly upload a photo or diagram highlighting which hoses to lookout for? Thanks for all the help

Have a read here. It basically the same thing over and over.

All sensors above 02SLOC fluctuate, ones below that stay about 0.700 or 0.720 constantly. I’m also getting a maf reading too of about 3.7-7.8 fluctuating. Again, not too technical with all of this so if any of this data can help any of you help me, that would be much appreciated. Thanks

In my last post, I thought you had the transmission out, not just a pan drop.

That said, have you looked under it for any exhaust leaks?

Went ahead and bit the bullet and replaced the b1s1 o2 sensor and did a computer reset. Fingers crossed no codes or problems come back. Was quite tedious with the ps computer because I’ve heard others have issues with recalibration but I’m good
