My wife and I bought a '95 vert last year to use as a cruiser, road trip, daily driver type of vehicle. We especially looked for a V6 for the gas milage, not knowing that gas was going to go so high this year. I'm getting 28/17 right now and that seems to be in line with what research said to expect. But I'd like to do whatever I could to bump that as high as possible. I have a bit of an EGR problem, so I intend to fix that. I'm also going to install a CAI system that I found on Ebay. (the full replacement one for around $48) The plugs look good, but is there anything to be gained by replacing them? The tranny is auto as well. I must say I was surprised by how lively the 3.4 was. Plenty of power for what I want out of this vehicle and a lot of fun to drive.
