99 Lightning

[Adonis Tijerina]

whats up guys so i just got a 99 lightning at a pretty good price looks great inside out but had been parked for a while now. while driving it back home truck started to get rough as it sort of idles while driving anything lower than 30mph and sometimes it shuts off. driving fast it has no issue it all feels good only while at idle or low drive it searches for idle and turns off? any clues of what might be causing it? it does have several codes on when i scanned it they inlcude

I know one of the codes is a missfire on coil number 4 if I'm not mistaken?
another one of them is maybe a bad oxygen sensor or so?
also its says its overboosting?

any help will be greatly appreciated

It could be a lot of things. I'd start by changing and reading the plugs.
