I have a 97 chevy tahoe which has the push button for 4wd you can push 4wd hi or low. I pushed low and the truck started running hard and sluggish and then the check engine light came on

If the check engine light is on, have the computer scanned to determine where the problem is coming from. Most parts stores will scan it for free. Also, remember, 4wd lo is only ment for expteme situations. Top speed is around 20 MPH.
