I am getting terrible milage (~18) in a D-jet 1.7, and individuals have suggested the MPS? Are there other symptons? How can I test? Anybody have a spare I can test?

first thing you can do is disconnect and plug the vaccum hose going to it and see if the car runs any different. If the MPS was messed up, chances are performance change would be noticable as well unless its just starting to go.

after that...you have to do the vaccuum pump bit which I'm not very knowledgable about, never had to do that. I think you have to pump it up no more than 15 in and it has to hold for awhile...

search the archives for specifics.
