Less than stellar gas mileage.

[RonPorter]

What can I do to get better gas mileage?

Start with 87 octane....

Naw I'm not an ******* at all, but yea it did throw the code when unplugged, but I took it to this hands on garage and they did i test! It came up as a bad MAF, he cleaned it and checked it again and it still read bad.

I'm not sure what you mean by "hands on garage".

What I'd suggest at this point, is to pull codes. See what the computer is telling you. Here's a link on how to do that with a paper clip, or a jumper wire: http://www.shotimes.com/php-bin/mod...le=article&mode=thread&order=0&thold=0&sid=83


Write down what codes are stored, and post them here. Doesn't matter if the check engine light is on or not, if there's anything wrong you'll have codes stored.

Hands on Garage is something that I know is in Milwaukee. Its a shop where you can go to work on your car yourself. You rent out a bay, they have all the tools you need and if you need help with anything the guys there will help you out. Its really cool, just don't have the bay rented to long. It gets pricey.

Can oil in the spark plug wells cause bad gas mileage? I changed the O2 sensors and fuel filer already. I'm planning on replacing the valve cover gaskets (and spark plugs) and I'm hoping this will solve the problem. I get around 14mpg in VERY light city driving, mainly coasting not going over 2500rpm. If I decide to step on it every now and again I probably get around 12 or less.
