Question about 2003 Pontiac Grand Am
If it is missing the check engine light will be flashing or may just be on.Is the check engine light on or flashing?If not then what you can do is remove the mas air flow sensor and clean it.It is located on the plastic tube part that goes to the air filter.You can get some mas air flow sensor cleaner and most part stores.Some people use brake clean but I figure if they make a special cleaner for it I know it won`t hurt the sensor.After cleaning it just let it air dry.Only takes about a minute.If you do have codes then you will have to retrieve them.Then you can post back and let me know what they are and I will be glad to help you solve the missing problem.Hope this helps.Good luck.
