You've likely got a bad fuel injector. I have my 95 E300 down for repairs right now because I had some glow plugs frozen in the cylinder head.

I have all of the tools to change everything on that engine. Bought it all.

My suggestion is to change all injectors and all glow plugs. I have a good source for Bosch injectors and glow plugs.
