Greetings - I seek your advice.
My much pampered 500SL has just been returned following a complete re-build of both heads - guides, seals, new left cam (right was previously replaced) new followers etc, new tensioner pads and left cam sprocket. Starting and performance is excellent but in-gear slow running is "lumpy" with what seems to be irregular partial miss. It is just not as smooth as before. Plugs/ leads/battery are fine. Injectors were replaced 6k ago. Ignition steady ar 16 BTDC - UK fuel. Can you help? Rgds, Bill |

A couple of things can cause this.
Low engine mounts, faulty ignition wire ends, etc.... ------------------ Benzmac: 1981 280GE SWB 1987 16V ASE CERTIFIED MASTER AUTO TECHNICIAN SERVICE MANAGER FOR 14 BAY FACILITY MERCEDES SPECIALIST 8 YRS PARTNER IN MERCEDESSHOP.COM |
