Guys/Gals, I really need some help here.

My truck is acting up, and I don’t know where to start.

So my father drove my truck home from a family vacation with my boat this past Thursday, and he said it ran fine the whole way.

My wife has been driving it all weekend while I’ve been out of town.

She called Saturday and said it’s smoking like crazy.

So I got home late last night and drove it to work today.

This morning it started up, and a decent amount of white smoke comes rolling out.

It’s rough at idle almost sounds like the lope tune is on. It clears up after about 30 seconds and sounds better, with less smoke too.

While driving to work, it’s missing in the lower RPMs.

It's not smoking the whole time I’m driving, but it’s definitely not 100% clear and definitely doesn't sound right.

So from what I’ve read, I fear injectors.

Here’s the setup on my truck:

2016 RAM Longhorn
80k miles
Tuned by DRD
5” straight pipe
ARP head studs
S&B intake
Grid heater Delete
Pusher ram air with hot and cold side piping
Stock fuel system

I changed the oil and fuel filters about 1 month ago, so they are basically new.

My father did fill up the truck on his way home, so maybe he got some bad fuel?

Do I need injectors at only 80k miles?

Should I stop driving the truck immediately?

Please help!

Thanks!
