well see if there is anything not working right making you run lean first...by dumping more fuell your not fixing the problem that made the car run lean in the first place....

Too lean is usually a vac leak, mass air flow meter, t.p. sensor, bad fuel pressure reg,stuck injector, bad gas,???? Could be number of things. How do you plan on making the adjustment to the fuel system yourself anyhow? Look at what your o2's are doing first if you can, you may just have a slow o2 popping that code.

I think fpdm is related to fuel pump. try new fuel filter then see if that will clear the code, if not my best bet is the fuel pump is not putting out enough, hmm reminds me of a girl i once knew

I think it's Fusl Pump Diagnostic Monitor, you may have a fuel pump about to go ****-up. Or it may be something in that curcuit that has too much resitancelike the relay or the inertia switch.
