Seems to be losing power at times then not at others kinda speratic, idk if something with the tranny or rear end, it's all wheel drive all the time no 4 lo or 2 wheel drive, it's the new v6 or 6 cylinder that jeep came out with after the 4.0 inline 6 cylinder, idk if there are related problems with these jeeps about power loss would appreciate the information thanks.

I have seen a bad MAF sensor cause this issue and I have have seen it not have a check engine light when this sensor starts to go bad. Check out the images (below). Let us know how it goes
