I recently (4 days ago) replaced my o2 sensors (front) and my spark plugs. My engine is responding much faster and feel stronger but I am burning through gas like crazy. Is this just my driving or something with the gar? aka gas filter?

 

Filter is inside the tank as part of the fuel pump. The ECU has to adapt to changes in the system, give it a few days.

 

thanks buzz!

 

interesting...let us know if it subsides.
I replaced an egr valve on one of my work trucks, at the first of summer...it went from 12.8 mpg to 10.1 and has not come back
