Hey guys haven’t been on in a while and have a question. I took my Jeep trail riding this weekend and it was very muddy. As soon as I got off the mountain it started to run rough. Anything over 2000-2500 rpm it just fall on its face. If I put it to the floor it clears out briefly and the does it again. Also coming to a stop it wants to shut off sometimes. Any ideas of where I should start?
 
Is it throwing any codes?

Now you know why I hate mud and avoid it at all costs. It just fucks shit up and will do so every single time.

If it's not throwing any codes, get an OBDII scanner with real-time live data. Plug it in while you're driving and monitor it closely. You should be able to read the data and see where the issue is coming from based on said data.
 
I haven’t checked to see if it has any codes I will go to auto zone to see if they can scan it and mud does cost money but it is so much fun haha
