Hello, i have never uploaded a file before, but hopefully this works and the following info can be of some use to you: http://www.filefactory.com/file/b2af194/n/fuelinjectors.pdf (if anyone knows of a better way to host a file please let me know )

From past experience, CLOGGED electronic fuel injectors seem to cause: 1. poor mileage and 2 poor performance.


NOTE *** A couple of the previous posters have posted info about their injectors, however we need to realize that there are numerous types of injectors out there. In Army's case i believe that he is talking about DIESEL INJECTORS which i believe can be cleaned and calibrated. and tilac1 i believe is refering to MECHANICAL INJECTORS(for a gasoline engine) and i am not sure wheter or not these can be calibrated.

to Latief. i have the same M104 as you, and we have ELECTRONIC FUEL Injectors, which can be ultrasonically cleaned, however from what the guy at the Bosch fuel injector service shop told me, they can not be calibrated. As long as the injectors are clean, they should all flow the same. he also mentioned that MB fuel injectors do not respond well to cleaning.

HAve your injectors flow tested, and make sure that they are all within atleast 5% of each other. all 6 of mine had nearly identical flow, however one of them leaked, so i had to replace it, because the leak caused rough startups.

good luck
