Nissan Repair: Engine cuts out, mass airflow sensor, air control valve


Question
Hello. I have a 90' infinite Q45 and it cuts out at a stop if I dont warm it up for a long time.  even after i warm it up it sometimes dies out at stops or while putting the car in reverse. is it hard/a lot to fix? and what exactly is wrong?

Answer
Matthew,

It is probably the mass airflow sensor or the idle air control valve.  You are going to need to get a book to show you the process of checking the codes since yours is pre-OBDII and that means that you have to check the codes on the on board computer.  The systems that I described are tested using a digital volt ohm meter and the process is pretty easy.  Get a Haynes Manual as it has the codes and how to read them along with the test procedures for the two devices I described.  Again, a pretty easy repair since both would be a plug and play job.
