To all my fellow Camaro fans/owners: I am recently in the market to buy a Cyber Gray Metallic 2SS, however I'm looking for used. Went to the dealership here in Las Vegas, and they had the exact car that I want. The mileage is 8600 with a cig burn on the back seat and the leather is flaking on...

my 95 3.4L seems to run pretty good but im only getting 16 MPG and i dont hot rod it, i mostly cruise at less than 2000 PRM and rarely get on it at all. are there possibly any sensors/etc that i should change to improve my mileage? any other suggestions? ...zimmy
