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>

check the ignition coil or plug wires. the injector is being shut off by the ecu due to a misfire.
