Ok I changed the valve cover gaskets on my 550i, 4.8l. I am getting a code for fuel injector 2, and a misfire. Codes 2e31, 29cc, 29ce. I swapped fuel injectors, spark plugs and coil packs, at different times. No change. Any ideals

 

Are you able to check compression on cylinder 2?

 

Unable to check that. I hear the injector activation.

 

Did you clear codes each time you swapped items and consistently get the same codes back?

 

Sorry for the inconvenience. The fault was my fault. I was chasing the wire and The connector from the fuel rail to the wire harness above the fuel rail. I pulled apart and the pin was bent that goes to the #2 fuel injector. I bent it straight and put dialect grease on it and put back together and everything is back to normal. No codes. Thank you for trying help.
