Hi everyone, I have a 04 Nissan Titan and every now and then when I start it up It will run and then cut off. Everytime I crank it it revs up a little and then the RPMS drop back down to an idle but sometimes it will Rev up and drop back down and just cut off. I asked a guy that works at the Nissan Dealership and he said it might be the Mass airflow sensor but he said it should be flashing a check engine light and it is not. It only does it maybe 2 or 3 times a month.
