I have a cousin that brought her POS Pathfinder to me to fix, I really
dont know where to start. Never worked on a Nissan before.

Apparently it sometimes stalls at stop lights. She can restart and it
will be fine after that. It sat for almost a year before she took it
back out to drive again. It didnt have any of these problems before it
sat.

I have searched and Mass Airflow seems to come up a lot. I will check
that but was wondering about some other ideas.

It also never seems to warm up just a needle above "C" on the temp
guage. I am wondering if it ever comes out of open loop. Or maybe the
guage isnt accurite.

Thanks in advance
