Which is never since it's summer in AZ.

If I don't get this corrected My car is going to be a lumpy POS come winter time.

Anyone have any idea why would this would occur. I never have lumpy idle while the a/c is on it seems. As soon as I turn it off it starts bouncing like a Q45 with a clogged injector.

Time for a dealer visit?

This is a very hard to fix p[roblem on our cars.

I got a new MAF and a grounding kit which took care of 2/3rds of it.

Dealers and techs are not eager to work on this as Nissan only remburses them teh standard diagnostic fee, and this is some thing that can take a good tech a full day of billable hours for which he will see little if any money.

Sometimes its bad injetor rings somehting coilpacks sometimes grounds.

the easist thing to adress is ground.

Some dealer will tell you, if no code = no problem.

Do you get the mild backfire too?

when a/c is on the idle map gets bit richer, combating what is really a misfire at lean idle.
