Idle sounds bad, do you have codes? Maybe misfiring? Hard to tell, but you should scan for issues.

Did you have oil consumption issues? Could be you need a carbon cleaning or maybe your catalytic converter is clogged with crud. I would think an injector would throw a code, but I haven't looked into that issue much.
