Hey Guys,
I was wondering if there were some specific things I could do to the S90 as a bit of a tuneup. I replaced the plugs already so they are good, timing belt has been replaced couple weeks ago. I plan on changing the oil soon, so while I'm at it I was thinking there might be some special spots to clean with Throttle body cleaner or something like that. I'd like to increase the fuel economy a bit, its getting about 23mpg of mostly driving on country roads 80-90km/h, with a bit of 110km/h and very little city driving.
Thanks,
