My foot is not in the gas.
Now a few months ago i did remove my thermostat to help keep car cool but it did not affect the mpg I will add before i leave today.

This just started yesterday out of the blue.

PS. I do not run any gas with eth in it.
Start by putting that t-stat back in. Taking that out can only cause you trouble.

Also, make sure you are running a stock t-stat if you are concerned at all about mileage.

Start there. But also consider plug wires and O2 sensor.
