Hey guys, I recently was on a road trip with my 2014 flex and about 500 miles into it I stepped on the gas and the engine Rebel up but didn't accelerate like normal. I kinda thought maybe I got bad gas or something and continued on.
Well upon further investigation I don't believe my turbos are spoiling, I do not have a CEL on, but when I check the codes with my SCT X4 I have a P0299. No smoke has blown out the exhaust. It drove fine before the trip also. Once trouble shooting started I watched boost in my tuner, it maxed out at 9 psi, and the waste gate will fluctuate sometimes, then just stay at 0.00.
I replaced the BOV's thinking maybe they were bad, and the rear one had oil on it. So possibly a rear turbo? I just need some help on how to further diagnose.
