Ive been getting really bad gas milage for about the last 2 weeks, only two things aftermarket are the pop charger and HKS sedan muffler for my 05 sedan. I have a ztube but havent installed it.

There's something wrong with my gas needle! it constantly shows the incorrect amount of fuel about everytime i start the car. It left me stranded all ready once and dont want that to happen again. Last night I used The last ten dollars of cash i had on me around 9pm and its fuel light came on wtf?

Also my muffler doesnt sound like it used to! any advice guys, I got a bumper to bumper third party warrenty but don know wat to do
