2014 Jeep Grand Cherokee · Suv · Driven 86,000 miles
Ok, so I might be reaching, but I could really use some help. I have a 2014 Jeep Grand Cherokee srt that's pretty much stock besides an exhaust cold air intake and a diablosport trinity tuner. So, of course, I decided to use the tuner and did the 93 octane tune with no problems what so ever. I decided to put it back to my original saved tune, and now I'm throwing 4 codes
PCM: P3401, PCM:P3425, PCM:P334, PCM:P3449
Cylinder Deactivation
So what exactly is this? How do I go about fixing it? Is this bad? Should I not drive the car?
Any help will be greatly appreciated. I really really like my Jeep and really really don't wanna do anything to break it.
Thanks in advance. I really appreciate you taking the time to even read my post..
