Finally got the muffler welded. One place wanted $175 just to weld it--it was already mounted. Found a place to do it for $75.
Once I got home from work I took it for a ride, but it feels like it has a miss or something. Took a pic of fuel trims, as usual I don't know how to decipher the info. 20220726_171414.jpg20220726_171333.jpg
Anyone have any insight/idea what's going on here? Running and sounds not so great. I took the pics in park while giving it some gas. Tia.

The short term trims are fine and those are your instant trims; anything within +/- 5 is great. Drive it a bit to see if they affect the long term trims -- those should come down if your STFTs are staying fairly solid as they sit now.

Might want to see if you can look at individual cylinder misfires, at idle and at 1,500 or 2k rpm, see if one cylinder is misbehaving.

I won't be able to look at it until this weekend. What could cause those fuel trims to be so off? Air/gasket leak of some kind? Bank 1 is the driver's side? Thanks for the info guys.
