So Monday of last week I put in new plugs and air filter thinking that MPG would change a bit and better then the 13MPG I was getting, I drove until last Friday and no changes at all. While packing up for a weekend trip last friday I remembered reading that disconnecting the bty would reset the computer and by doing so MPG would change. So while packing I disconnected the negative for 20 minutes or so, hooked it up again and off I went. I seen a change, HWY over 16 MPG and city now over 14 almost 15MPG depending on my foot. I'm not sure disconnecting is what made the change but if so it was worth the minute it took to disconnect and connect.
