Tahoe 4wd 1998, Cleaned Air filter with water, put it back with some humidity still in Air Filter, now I have the warning "Service Engine Soon", and when engine is warn, truck have little aceleration, Do you have any sugestion on how to fix it?

Sounds like you may have left a hose loose or off which is causing a problem with the Mass Air Flow sensor. Hopefully this was not a paper filter you cleaned with water. If so, replace it.

Went to "Auto Zone", got computer code P0785: Shift/timing selenoid mal function. How a little humidity in air filter can damage a transmition?!!!
