This is my wife's vehicle and I am stationed elsewhere for the time being. I was hoping someone can maybe point me in the right direction with an issue she has with it. Once in awhile when she starts it the Jeep will rumble and shake and make noise under the hood. I am thinking it is in limp mode. She has to turn it off and turn it back on a number of times for it to run properly. It has 40K miles and has been serviced regularly. It does have a pressure box on it, cant remember the brand and an MBRP exhaust and K&N drop in replacement filter. Any help or tips would be appreciated.
