Hi Byron

Try leaving the air cleaner on but disconnecting the mass air flow sensor, then start the truck and see if it runs like the air filter is off.

Let me know.

hi mike V i dissconected mass flow sensor& it would not run?any other ideas?
Nissan Mechanic: Mike V., Nissan Technician replied 2 years ago

May seem a stupid question, but is the air filter clean?

Also check the oil and see if it smells like fuel, if it does the truck may be flooding out due to fuel vapors in the oil coming into the engine through the breather.

Sorry that's all I have for you on this. I am going to open it back up for the other experts. We have a couple of Nissan techs with a bit more experience that might be able to help out. Please DO NOT reply to me or it will lock it to me. Try to be patient, one is likely going to pick this up.
