If there is any forum that has the answers, it's going to be JeepLab. Anyone here run into this?

I've had the same problem with them codes. I installed mine last May and been lighting them codes about every 150-200 miles and jeep still has a slight miss around 2000 rpm. Clear the code and it comes back over and over. I contacted Ripp and its kinda of a run around with data logging and emailed them. I'm hopping to get with a tuner locally soon but they are few and far between here. Let me know what you find out. Wish I had more time to dig with the problem but gotta work to pay for the toys
