Hi Scotty, Love your videos.

I have a 2012 Enclave that randomly seem to lose power just for a second or 2 while at cruising speed, flat terrain, and while driving North Carolina mountain roads. My wife, the primary driver of this car, describes it as a fast chug-chug feeling.

I have been banging my head on the hood (btw, that hasn't fixed the issue and I'm spending a lot more on Tylenol these days) and I'm at a loss trying to track down the cause of this symptom.

Here's the details on the car:

2012 Enclave V6 AWD 154000 miles. To the best of my knowledge the issue started right after she let the battery drain to the point it would not start. I jumped the car and she drive home. The battery was replaced due to its age and very short reserve.

At the time I got a code that said the eprom needed to be flashed, but the code went away so I didn't follow up on it.

List of things I have done:

Changed both engine and cabin air filters.

Replaced both spark plugs and coil packs on all 6 cylinders.

Replaced valve cover gasket due to oil in #1 & #3 sparkplug tubes. (oil all over the 2 spark plugs the rest were worn but dry)

Replaced crank shaft position sensor because of something I read somewhere... That was a PIA due to the AWD transfer case being right in the way... ugg.

Any ideas? I'm hoping you have seen this before and can help stop the torment this car has been giving me.

Thanks in advance. Russ W
