Mine had the same pop after I did the front control arms. Turns out my preloaded torque readings were garbage. On the alignment rack they were so loose I could have wiggled it with a wrench and it would have come undone right there. Apparently the driving and bouncing and stuff loosened it up.
That was the one time I went against my usual routine of using my 3/8" long rachet and giving it a good turn to tighten it up. Once I did that, the noise was gone.
Ive also replaced everything in the front end of mine. Ball joints, shocks/top hats, and powerflex thrust arm bushings.
As far as the codes for too rich/lean, my MAF was NOT the culprit. The CCV setup had numerous cracks in it so I deleted that all in favor for an aluminum M56 valve cover setup. Since then I've had zero codes, truck starts up and runs just fine in the cold, and my oil consumption actually went down.
Have a look down there and see what you find. At 196k, if it hasnt been changed at least once, it definitely needs to go now and get deleted or all the parts replaced. Could solve a good portion of your misfire issues.
