My Nissan dies shortly after starting. Checked onboard computer code 13 for Mass Air Flow sensor. Replace engine temp sensor, 02 sensor and water temp sensor. I can't seem to locate a vaccum diagram on this vehicle so I'm 100% sure all the lines are correctly connected. Is there anyway to test this air flow sensor as it is very pricey? I bought this vehicle as a project and it's been a nightmare! Any help greatly appreciated. Please send diagram to pstephens1@satx. Rr. Com. This vehicle has a replacement motor so I'm sure of the miles over 200000 on odometer
