Engine Misfires on Cayenne

[oscaac]

Hi All,

So today, after putting gas (Shell, premium) in my 2014 Cayenne base, I got on the freeway and shortly after, the check engine light came on and Cayenne started shaking abnormally. I was able to turn around and get back home but I noticed 

1. When I stop, the CEL flashes and the Cayenne shakes a lot more

2. When I press on the gas, it takes a long time to pick up speed (really struggling). 

 

I connected the Durametric when I got home and I see the following misfire fault codes on it.

 

Anyone have any suggestions? Cayenne has around 62k miles on it.

You have multiple cylinder misfires, a common problem on these vehicles when they develop coil pack issues.  I would plan on pulling the coils and plugs with an eye towards replacing several.

I'd be inclined to also check for water in the Shell Premium.

Thanks all. So it I took it to an Indy shop and the first thing they noticed was one of the coils had rust. Not sure if the previous owner/dealership pressure washed the engine before I got it but I guess I need to replace all the spark plugs and coils anyway.

Loren posted that he would also check the battery and ground wire for corrosion. I hope he is right, but just in case, what did the coil and plug replacement set you back?
