We have a 8.2L turbo-charged engine ( I know, I know--but we are stuck with it) and it has 79,120 miles on it. Idles rough until warmed up, sucks fuel like a fire truck siphon, will go nicely down the highway for a bit---constantly spewing light blue exhaust--then suddenly stumbles and loses power until down to around 30 MPH. Engine running rough, then slowly takes off again. Used to run great. Started up super well, got 8+ MPG, and had decent power. OH, coach did sit in storage for nine years, many years ago, but has been driven the last 12 years.


Injectors the problem? I did drain the fuel tank, refilled with clean fuel and a Biocide, and changed primary & secondary filters four times.

Can't seem to find anyone up here in Central Wisconsin with knowledge of 8.2T

It sounds like you are drawing air (crack in the draw tube, pin hole in a suction line) or you have a fuel line collapsing or something in the line. The supply pump seal could be hard as well.

Thanks, JoeZ. Now I have to find out where these parts are, what they look like, and how to test them.

The 8.2 mechanic up here has come back from Texas but it seems he will not return my calls so I am in "deep, deep DOO-DOO" until I can find someone else around here that has worked on 8.2 DD

Is it possible I did some damage to the injectors when I overdosed the fuel tank with Startron and Sea Foam additives because I was under the assumption we had an algae problem again, or water?
We did make a 240 mile trip this spring with no problems. This, after putting 1 bottle of Startron additive in the tank before putting the coach in storage last fall. Is it possible some crap came loose and plugged/destroyed injector(s)?
