Can a bad diesel cause a rough running engine?

[kf6ivi]

, sound like it has a miss? I had filled up the day before go to work on my way to work I noticed that my engine did not sound like it normal self. I noted a miss like sound and white smoke that smells like diesel. I have lost power with this.

I have loosed the injectors to see if I had an injector go bad. All the injectors caused and small drop in engine speed and a slight increase in rough engine noise. I have put my diesel additive in the fuel today. I plan on changing the fuel filter today.

I have no signs of air leak, the motor starters right up even if left sitting two weeks without use.

What else can I check?

Thanks Ethan

pop the valve covers and look for loose springs or anything that looks out of norm.
