I'm guessing it's the GMS1, lower charge pipe sensor. It's either loose or the dealer didn't solder the wires.

Some of the older Dejon Intake that Ive seen didn't have the proper Breather Fitting on it and the hose just sat on there. If that comes off it will create a Post MAF Airleak and cause issues.

If you want to run the BOV with the least amount of issues, you should consider doing a MAF relocate and getting a real tune for the car. It is possible to leave it in the stock location and tune it but it's better with the relocate. You CAN NOT do a MAF relocate without a real tune, don't even try it!

check the sensors first they could be going bad or have a loose connection

I had this issue too. My AFR would bounce like a set of double Ds in a porn movie and it was driving me crazy. The car would buck like a bull at a PBR show.... anyways I took it in at the dealer and they soldered the wires and relocated them to run just above the AC line to prevent dondensation from dripping on them. Two weeks since they fixed the lower charge pipe sensor by soldering it and I've had no issues. If you do end up taking it in to the dealer tell them to solder the wires and to relocate them to run above the AC line. Worked for me :cssNET:
