Hello all. I’m new here. I came here because I need help. My Journey is not running very good lately. It has a bit of a rough idle. When driving down the roads (after it warms up a bit). It will start to shudder (I guess you would say that). It starts to shake and rattle some. I know it has something to do with either spark or fuel delivery because it doesn’t do it all the time. It starts its shuttering thing somewhere between 30 to 40 mph. Then it will stop and run good and smooth at 75 to 80 mph. I have the red lightning bolt in parentheses on the dash most of the time. The check engine light is on. I can’t get the codes because my obd port don’t work. I can’t find the fuse to replace it because I have an SXT model and haven’t found anything online pointing in the right direction. I have already replaced the crankshaft position sensor, throttle body, and mass airflow sensor. I am getting to the point where I’m at a loss and don’t know where to go next. If someone could please help it would be greatly appreciated. This is our only vehicle and my wife is a double above knee amputee. We need this car for her doctor appointments and getting the kids to school.

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!
