I need some ideas on what to replace. I just ordered an O2 sensor and a new CAT is on the way also.

I took a trip yesterday over to the shore yesterday, so the tank was use for 1/4 city, 3/4 highway. I got 17.somthing mpg. AHH...I noramally will get 18ish CITY and 25ish highway. Although the tank before this one I got 16something city.

What has gone bad. I just cleaned the K&N before the road trip (gutted the air box too).

any ideas on why my gas mileage is so bad?

those two tanks my driving was "nicer" than normal because I had passengers. And even when I am alone and drive the **** out of the car I have never seen it bad.

It could be the recent mods. Could be bad gas. Could be almost anything.....

I'd consider where you picked up the fuel. Sometimes a place with get a bad batch or two.

A quick bit of humor: Guys...he'* got an SE..how bad could his driving habits be?

I've said it before and I'll say it again. The only thing that whines louder than our SUPERCHARGERS are the people that don't have them.
