Car starts but wont accelerate

Have a 2003 Nissan Maxima, just got but been sitting from previous owner
for over 6 months, got codes P0507, P0430, P0420, P0011, P1448, due to
one of the codes saying clogged because I really don't know, I drove it for a
day and half around my house and it seemed to drive ok but after the
codes I bought fuel cleaner that states put it in while gas was half full, after
I put that in drove probably about 4 miles or so and as I turned to go up a
hill it wouldn't accelerate, turned off car for a few minutes, started it up and
go to go a few feet driving up the hill (did this 3 times) then I just had
someone behind me pushing it while I was in neutral to get off the road,
after I parked it tried to let it sit and when I started it still no acceleration.  I
know I got the codes that seem major but still was hoping that some
flushing or cleaning would do some of the work due to it been sitting for so
long
