Hi all I own numerous Diesel Mercedes but have a friend who has a 1995 E420 that is low on power. The car has 257K on it. It has the 256 CID engine. He took it to a dealership he said they replaced the spark plugs and distributors (hope that sounds right), and the car is still underpowered, he's afraid maybe the injectors are bad? Anyone have any idea's what could be causing his problems?

Thanks in advance,
Justin

 

I wonder if it could be a fuel delivery problem..fuel pump or filters?

Thanks

 

No idea's or suggestions? Any info would be appreciated!

Thanks,
Justin
