timing problem with c300 engine m272
a few days ago I had a problem with the engine timing chain so id had it replace by a mechanic apparently we put all the timing marks in its position as indicated in the wis manual so now the car stars but the engine docent fill right it vibrates and when I try to adjust the timing solenoids with a launge scanner it says that it could not be performed any idea what we did wrong when puting apart is there something extra I need to do with de cam selenoids and magnets
regards
