Hey there,

New to the forum. Need some advice with my car. It was running fine until yesterday, now the ending is revving up, going down, back up, then down to a slow choke and shuts off. I switched out the battery today as it was the original still in there and thought I may just be having power issues. I haven't switched the auxiliary as I can't find one near me yet, and I don't think it would be causing these issues anyways. Any advice is much appreciated! I can't upload the video so I will share link here.

Video does not work.

Which engine?

 

According to his profile it's a 2015 3.0.
Which would make it the AJ126.
I can't help with the revs up and down issue but the secondary/auxiliary battery cannot have anything to do with that problem.

 

I've had hunting / stalling a few times with my car, cleaning the MAF sensors usually sorts it out.
