I have a dumb question. I was messin with the vacuum wipers to try to get them to work. I had them on quite a while (5 to 10 minutes after a 20 minute drive) with the truck idling.

As I was messin with them I noticed some grey smoke coming out the exhaust. I revved it up and it ran a little rough and more smoke. It seemed to be missing some too puffin out the tail pipe.

It did not seem like oil smoke or unburned fuel. I was wondering if I since I was running the wipers so long at idle and they suck up vacuum that maybe that would cause some smoke condition...ie a rich fuel mix.

This engine is new and never smoked before.
