2003 Blazer 4.3 fuel mileage help
#1
I need to help this thing get better gas mileage, Do the throttle body spacers and cold air kits help at all? Any other suggestions?
Thanks

What kinda mileage are you getting are you a four door or two door, stock tires suspension etc. Bout 16.5-19 at the best is all you are going to get out of most of them especially if it has crappy 3:42 gears. If it has 3:42's there is part of your problem because it is constantly laboring.
