Have been having a hard time finding a good service/ shop manual for the 1990 300CE. Am looking to replace fuel injectors before I leave on 3 week road trip on the 30th. Any suggestions where I could order in a factory manual, or download the appropriate info, for a fee or course, in the next day or two? Have all of the parts, but a little direction would be wise I think. Any help would be greatly appreciated.

I have the same problem finding the manual for the '88 300CE as all manuals I've found either don't cover the model or don't cover the year.

The way to go (though pricy about $150) is to order the factory CD from Phill:

1-888-333-4642 or philip@peachparts.com

...the provider of this site.

Or the parts seller of your chioce.

It is not the most intuitive manual but it is the most complete.

I did not realize there was a store directly connected to the web site, I should have dug deeper. Accidently ran across an online site"All Data".
$12.95 /yr. access to a reasonably in-depth shop manual data base that you can download and print off service and repair diagrams and proceedures, along with all specifications for the year make and model.
