I took my car in to a local forestone where they replaced the radiator. The day I picked it up I noticed a wobbling/shaking while in idle, and it had NEVER done that! Is there anything that could have happened while they were doing that? I still get 22-23 mpg and never had issues and maintenence it by the book. SO what could be wrong?

Hello Infiniti01

The first thing you could do when you noticed the car shaking is to take it back immediately to Firestone and explain what the problem is and do not let many days go by.
The shaking at idle could be cause by lose parts or the engine is misfiring due to partially unplug spark plug boot or the tech when changing the radiator and reaching the automatic trans axle fluid lines have bump or accidentally disconnect sensor wiring because those lines are hard to reach.
If there is no engine light, the shaking may be lose part.
You can take it to Firestone and ask them to recheck their job and it should not cost you anything.
You could also have it diagnose and look for pending code if there is no engine light and report to us so we can continue.
