i have a 97 maxima and it is misfiring. I took it to autozone and
they put it in diagnistics and came uo with a code that stated that it
has an ignition misfire(duh) and speed sensor and intake air temp
sensor. They do not stock these parts and they really didnt answer
the question of why is it misfiring. Can anyone offer me some
guidance?

the answer lies with the codes scanned from the AutoZone dealer (duh),you
have the information to start your diagnosis so get busy and figure out
what's making it miss.

Most times scanning the codes and replacing part does not fix a thing, but
sometimes it does. That is where a real technician comes in, not just a
parts changer.

Hmmmmm missfire...

What are the causes of a missfire gang......
I'll start.

Lean air fuel mixture missfire due to excessive exhaust gas (EGR) entering a
particular cylinder .The old P0400 code

You might also want to check the ignition coils, since this is easy to
do. From what I read the coils on this generation Max are prone to
failure as the car ages. Another area to check is a vacuum or intake
leak, which could cause lean misfire.

Have you ruled out the basic tuneup?
