Lean?

[Moparornocar0346]

Ok so let me start by saying that I have a 99 ram with the 5.9 magnum auto, I hooked it up today to check for codes today bc I had a bad misfire on the interstate. Check engine light came on for a split second and went off. Misfire stopped still not misfire as of right now. But I went into live data and it is showing a lean condition? Now what’s the first thing I should look at for this issue. Like I said no codes. So there for I don’t know where to start. O2 maybe? Plugs? Weak coil pack?
