Waynedog,

You should switch to a different dealer to service your car. Those engines are pretty much bullet proof, and it should not idle rough ever.

 

I doubt he is reading this thread considering it is from 2013...

 

Has anyone here ever tried seafoam in their engines? Its supposed to clean out all the gunk and make the engine run smoother and more efficient.

 

Mine has 108 on it and it runs great, probably due to first owner keeping the car up, I think everything has been replaced at least once, car is like I rocket ship. Having said that I love my car, but not sure how much more mileage I want to put on it before I sell, now in ending the last time I heard about Seafoam was on the BMW 7 series forum, where that powertrain is way more sensitive and touchy. My own opinion I wouldn't go that route. Now when I had my 280Z I'd put anything in that engine and it would run, had about 300+ on when it passed, chicks loved that car lol
