Had my spark plugs replaced for 283. I warned them of the problems but they said no big deal and charged me for an hour and a half labor. 16 hours later i think they were glade to be done with it. And since it took so long they put my cop's in for free. Only one plug broke.

 

Sounds like a damn good deal! (aside from the wait)

 

I was at 71,xxx miles and the plugs were shot. I have been trying to do preventive maintenance to avoid any problems since my warranty has expired. With help from this site I think I am going to tackle the injectors next.
