Re: 01 Jetta 1.8T - rough idle

Hopefully it won't return  My wife's '00 1.8t Jetta had the same thing
happen and fix only to return on occasion. They did replace some sort of
turbo valve as well. From what I have read here, it could be the NGK plugs I
installed. Will need to replace them soon, but hate to pay around $70 for
four OEM plugs.
