1997 c230 injector problems please help!!

I recently purchased a 1997 mercedes c230. It was running rough when i purchased it. Was throwing codes for maf and iat. so i replaced the maf. now the codes are gone and its still running rough. So i did more testing and found out i was loosing power to my #4 injector. Its coming and going sometimes it fires some times it doesnt. anyone have any insite on why this is occuring?

any help would be great. I am very mechanically inclined>

Have you tried running any fuel injector cleaner?A can of seafoam should help and change your fuel filter.

Is this something you plug directly into the rail? I am not familiar with these and would like to know more.

they are a series of several different small lights that you plug into a circuit you think is bad and if it lights there is power to the plug/connector......try Ebay or do a google search for more info
