Check your o2 sensor also , bad reading can cause bad *** milage if it is reading incorrect!

no cel...

ok here's the odd part...

i gassed up 5 gallons the other day, and i decided to drive very slowly and not hit vtec...

well driving 70-75 shifting b4 4k, my gas mileage went up, im averaging now about 25mpg...

can hitting vtec daily kill my gas mileage by that much? from 18 to 25 by just shifting earlier and driving around 70-75?

Thanks
