Are you having a problem or are you trying to get better mileage than the vehicle would normally get?
If you are trying to fix a problem, and want to avoid paying for a diagnosis, then I wouldn't take this approach. You will end up having to get it diagnosed eventually, and probably after replacing unneeded parts, so either diagnose it yourself or pay to have it done.
