Question

how can fix my 2004 nissan armada code show up PO307

Answer 1

for P0307 if you have not replaced the spark plugs start there, use oem spark plugs

for P0507 the throttle body is most likely dirty, which needs to be cleaned and do any idle air relean

see instructions for idle air relean below
