okay so if that does work, what do you think the next step would be?
Nissan Mechanic: david craig, ASE Certified Technician replied 11 months ago

it probably wont work, you dont have a maf code. clean the sensor anyway. plus you need a vent control shutoff valve. also with the engine running, remove the oil filler cap and put your hand over the hole. tell me if you feel suction

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
