1999 Pontiac Grand Prix 6 cyl 86000 miles

ok I replaced the mass air flow sensor, now my car is doing the same thing I had the computer cleared and reset and still having the same problem and the problem is that my rpm's go up to 4,000 and drop almost all the way down below 1,000 and sputter and die and it also does it while driving around corners or stopsigns lights, or even costing down hill it will just die. But the code that was read after replacing mass air flow sensor is that lean bank 1 and that has to deal with my full injetor but would this cause the problem or any thing with fuel pump or fuel filter.

Do you
have the same problem?
Yes
No

What is the trouble code? Why did you change the MAF sensor?
What is the fuel pressure? And how fast does the fuel pressure drain down after the engine is off?
