I'm experiencing the same issue except I have JB4, so frustrated with it. Stock map it's fine 100% of the time.

I have had the HPFP, plugs, coilpacks and injectors replaced so far..... Not sure what the dealer will throw at it next.

My idle is a little rough too, I will be getting a walnut blasting and hope that finally remedies all my issues.

wow that sucks dude! im going to go the injector route. theres a nice DIY even for coding so im going to do that, ive done everything except injectors and carbon cleaning. Im hoping i dont have to do the carbon cleaning because ive read a couple of threads seems to be
expensive!!!!

Quick update ! It was the injector in cyl 3 ended up replacing injectors in cyl 1,2, 3.
It first started getting the error code with the Cobb, then I removed the Cobb it ran smooth for a week, then I got the ses light. Would turn it off with the Cobb and it would keep coming back quicker after time. After I swapped the injectors good as new. Codes and swapped myself with the DIY on the forum and help from ppl on the forum. Anyways if your having this prob check the obvious spark plugs, coils, thEn injectors. Those were the culprit . Thanks !
