Ok, i got the scanner...what im looking for?
Nissan Mechanic: Ivan Alvarez,
 replied 8 months ago

First scan for codes. Then with it idling look at the throttle position reading, and mass air flow reading. Let me know where those are at. You mentioned the idle goes up and down now so give me the readings at the low point and high point.

O​k I'm going to review some info for the codes. With the key off disconnect the mass air flow sensor and start the car. is the idle stable or does it still surge?

After doing this connect the mass air flow again and clear all codes. Then restart it and scan for codes again and see what returns.
