In reguards to IGNITION TIMING ADVANCE: How long does it take for the car to complete the idle air vol process after changing your ignition timing? Cuz everything went well with the ign adv, turned the car off waited 10 seconds turned it back on, try to perform the idle air vol learn process waited 5 minutes and it just kept saying please wait. So I dunno Ive heard people saying the whole process takes 2 minutes!!! Please Help??

 

Just drive it, it'll relearn on its own...

 

The Nissan tech who advanced mine told me to stand on the gas for about 100 miles and it would relearn it at a higher-than-before map.
