i have '12 JKU Rubi w/ 110,000 mi., she is having issue when I start her up from cold engine runs fine. Reverse out if driveway fine. Put in drive and try to accelerate forward and she bogs down with little to no movement forward. Engine does not race but does not die either. After couple of attempts to get her moving she will start acting normal and accelerate and shift fine. I can remote start her and after about 5+/- minutes she will not have the bog/hesitation. The only CEL I'm getting is Bank 1 catalyst. Just changed trans fluid and filter yesterday no change. she is also having minor issue with down shift from 3-2 and 2-1 occasionally.
Any ideas.
