Thanks M.B. Doc, that was the part I think I need however I cannot find a good link. I am trying to contact Bosh. I'll let ya know how it works.

In the mean time I ran a bottle of Redline Intake Cleaner thru fuel system which helped smooth idol a bit. But after selecting "park" idol sets at between 1200 and 2500 rpm. Not as bad as before but still high.

Thanks
