1994 7.3 idi with a turbo will idle all day long and starts up like its a brand new truck. When it gets past 1000 rpms it starts stumbling and will blow like a faint blueish type smoke. Its not a really thick white smoke like injectors. This truck has brand new glow plugs, injector pump and the new not reman injectors have maybe 20 minutes of run time on them. Im kind of at a loss. I can rev it up past 1000 rpms itll stumble and then when i go back to idle it idles normal. I have videos too if you want i can post them and send a link. This truck does have quite a bit of blow by also. Any help would be appreciated, just trying to get her back on the road, thanks!
