Well, I filled up today at a half tank left (because I just changed my fuel filter) and I am happy to report that for the first half of the tank was 31 mpg!
So I am attributing the increase to 3 things: 1- Increased tire pressure (from 35 to 45). 2- I took out that massive sounds system and the 0 gauge wiring that accompanied it (it weight a ton!). 3- I adjusted the nut behind the wheel
As far as the O2 sensors go, I have both of them, but the socket to remove them will come on Wednesday.......
On another note......I ordered projectors for my Civic cx to do a little retrofit.
