Brakes it can be. check contacpoint.
SOURCE: what are the possible reasons for high fuel consumption?
a low cylinder will cause a reduction in fuel economy. also in the winter months many states oxygenate thier fuel, it helps with emmisions but reduces economy. higher octane fuel usually has less feul economy, drop to the mid grade

Try checking your Spark plugs (they MUST be the right type, clean, and properly adjusted: and try adjusting your timing. Either or both of these could cause this type of problem Hope it helps. If so, don't forget to rate the answer, will you?

change o2 sensors every 60,000 miles and use iridium plugs they will outlast engine.
check engine light will not come on until sensors are completely shot,this also goes for your mass air flow,had same issues with 99 beetle happened at 80,000 miles,changed all three items ended up with 35mpg after getting 24mpg before fix.parts are cheap on ebay.

hey, I own an 04 v6 mazda 6 as well and recently had that same problem. Its an ignition coil. The thing is that you have to wait until the check engine light comes on to know whick cylinder it is. I replaced all my spark plugs and boots all at once thinking it would solve the problem but it didnt work. It takes a while for the light to come on so what I did was to push my engine and make it come on. Hopefully its one of the the three coils in the front or else it would be a pain to get the back three. Each coil will run you about 50-80 dollars. Call me if you have any questions.
