Right now I am getting half the gas millage I used to get
with city driving. I have not changed my driving. Same job same distance. Engine is running good, no engine
check light just bad gas millage down to 5 to 8 MPG.
What is going on. Do I need a tune?

Ther are several cheap things to do here, but at 90k you should of already had a tune up. 1st off you need to change your air filter. Get a K&N, it never goes bad (you buy a recharge kit, clean it and recharge it) This will give you more power and better MPG. Also check your tire pressure and size (size if you just got new ones) Get some fuel injector cleaner, and get that tune up. Also is your idle speed correct? Also keep in mind that a lot of after market parts that increase horse power may increase MPG
