Do you have any idea when the instant fuel economy monitor on the dash changes erraticly when selected. I realize that it will be changing all the time, but it jumps continuesly when driving at contant speeds.
Thanks

Re: 2002 envoy dash fuel economy reading are erraticly chang
It all depends on the situation. Sometimes it can remain steady, and other times it will jump all over the place. Also depends on the quality of fuel you're using as well. It should be nothing to worry about.
