Default Throwing a code and a bouncy idle...

I forgot to ask this question.
When at the dealer, the check engine light came on. The code was "P1114" Mixture Issue. He deleted the code to see if it would cure it's self. So far it hasnt came back on, but, the car will randomly get a bouncy idle almost like it's going to stall (at a stand still). I've only had the car a day and mon/tue look warm, so I guess ill start to learn what's where.
Any one else ever gotten that code/bouncy idle situation?

Either your MAF is failing or the Throttle valve is in need of a good cleaning.

After reading a few posts, im understanding that if I unplug the MAF while the cars at idle. If the MAF is fault the ECU should pickup on a default map and the bouncy idle should stop? I'll check into the Throttle valve as well.

Unplugging the MAF is a way to diagnose a bad MAF. If the problem persists with the MAF unplugged, then you'll need to look elsewhere at the problem. Another problem may be a vacuum/boost leak in the system, that will also give you a lean code. In order to find that you'll need to pressure test the system.
