I have been getting 17 mpg on my car for the last six months. When I bought the car back in Febuary it was giving me 23+ average. I did the cap/rotor, plugs/wires, sea foam, cleaned out the v-tec solinoid, New oem tranny oil flush, & the oil changes are done every 4 thousand miles. Any suggestion? I have read a lot of the other threads regarding this, but I already tried most of the solutions I have read. My next move is to buy the two o2 sensors and replace those along with checking the flow on my injectors.
