Last year I had to put almost $15k into my 2015 LT - half of the fuel injectors failed, spark plugs, catalytic converter, and a new transmission. It had driven fine since then, until about a month ago when I noticed the familiar shaking while idling and some other symptoms. The dealership told me I need to have the number 2 injector replaced - the good news is that it's under warranty from last year. However, the dealership is also recommending two additional services - throttle body cleaning and an injection service. Of course I am weary about listening to anything the dealership says. Is anyone familiar with these procedures and, if so, are they actually worth it? Together it would be around $500 for both.

If not, I'm going to lose at least a week's worth of gains from options recently.
