Hey guys,

I have been getting horrible gas milage lately. I used to get around 18-20 miles p.gallon, but the last 5 or 6 tanks, I have been getting aroun 12.5 miles per gallons. What could be the cause of this? I have tried all different octane rating without any change. I have even been trying to keep my rpm's under 3000.
I appreciate all suggestions.
Thanks


Oh, almost forgot, I have a 97 s-10 Blazer (2door).

have you replaced your fuel filter and spark plugs lately? How many miles are on the Blazer? What about cap and rotor, spark plug wires, and air filter?

Have you checked the air pressure in your tires? Also your coil might need to be replaced.

Check normal tune up stuff... Start with the 02 sensor.... Cap, rotor, plugs, wires, fuel filter, PCV Valve, then check injectors, tire pressure, air filter (switch to a k&n if you already haven't)...Check for leaking vaccume hose...
