My sister n laws xj keeps stallin she can be at a dead stop or going 30mph down the road. Or up on the interstate. The jeep is not throwing a code and the jeep dealer cant figure it out either. Checked the fuel pressure its good checked the ground straps i dont know what else to check all fluid levels r good and nothing wrong. Anyone have any ideas. Thanks Jimmy

Do all the dash lights come on when it stalls out, or is it blank like there is no juice at all?Throttle position sensor?
Crank Position sensor?
