Good day all,
My 500SEL has been at a reputable Mercedes specialist for a while now and they have rebuilt the engine. They are struggling to get it running sweet again so I hope you all can shed some light please... Symptoms include, running fine when cold and idling. When engine warms up and it is put under load, it is hesitating and running lumpy. I have been told the following has been changed/looked at after the full bottom end up rebuild using genuine parts-
Dizzy cap and rotor
HT leads
Cam sensor at the front of the engine
New injectors
New fuel filters
New spark plugs
Fuel pumps are working as they should be
Hopefully you can help sort this so I can get my car back. I’m sure I’ve missed a couple of things but if they are pointed out, it’ll jog my memory.
Thanks in advance.
