idle shake

[slpin]

sometimes, the truck shakes at idle, not too much, just a bit, kinda like someone pushing it on the side lightly, is it normal for it to not be smooth?

Tell us a little about your truck, what mods you have, etc. That might help find out whats going on. Also, have you recently serviced, oil, fuel filters, etc?
