Wow, thanks for the fast replies, especially on Thanksgiving Day! My car only has 9500 miles on her so I have some more snooping around before bringing it in to the dealership. I don't have a wideband since the Autozone guy gave me the code.

Do you think the dealership will re-flash the computer? Don't want to mail in my ECU to LET again.

Maybe a colder plug may solve this problem???
