98 Millenia TERRIBLE gas mileage...

Hi all...

My car (well, my brother's) car gets about 12MPG. It used to get 18MPG (not great still) before I gave it to him, but the situation seems to have worsened already.

The Check Engine light has been on for longer than I can remember, and I was told it was the #2 Knock Sensor... I am not sure how this affects my mileage, and whether it can be worsened over time as it has been.

I appreciate any help in this regard.

Of course it will affect your mileage, it changes timing. You just can't ignore warning lights and then ask why is it not running perfect. Have it scanned again and see what's in there then post the numbers back here. In the meantime check you tire pressure and air filter.
