My \'97 2wd is only gettin 14mpg... Whats up??? My '97 2wd Ext cab Chevy is only gettin around 14 mpg. I don't drive it hard. It's only performance mod is a K&N (No noticable improvement after the K&N by the way). Everyone else I know with a '96-99, Tahoe or truck, is gettin close to 20 mpg. As far as I can tell from drivin around town, it does not have the lower 3.73 gear option other people have suggested; though I'm tempted to pop the cover off and count the teath to be sure. Any ideas??? Thanks! <font color=black> -Tommy <font color=red>"To secure peace is to prepare for war..."
