[quote]As far as the CSV dribbling fuel; thats why my initial question is if anyone knows where it is located. Also, how would I check the cold control pressure?

With a set of CIS gauges, same ones as you would use on a 911. PP sells them, although a lot of folks prefer the $60 Sears set.

Thanks everyone for the input. If anyone has an idea where its located let me know.
Heck, I don't even know where mine is...

Here's a picture of one though, might help.



It's even the correct one for your car, from http://cgi.ebay.com/ebaymotors/Mercedes-cold-start-valve-280-380-450-560-SE-SEC-SEL-SL_W0QQcmdZViewItemQQ_trkparmsZ65Q3a12Q7c66Q3a2Q7c 39Q3a1Q7c72Q3a1205Q7c293Q3a1Q7c294Q3a50QQ_trksidZp 3286Q2ec0Q2em14QQhashZitem4cea24004eQQitemZ3303457 42414QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessori es auction.

See it's got an electrical connector AND a fuel line? You'd think it shouldn't be all that hard to find

It'll be on the inlet manifold somewhere...
