I did get 1 coil replaced a few months ago while it was still under warrantee. I'm about to take it in for 40K service (has less than 30K miles but its 4 years). Only use 91 octane. I'll see if I can get the dealer to give me the codes when I go. -- Posted via a free Usenet account from http://www.teranews.com |
