Help! My 2012 Jeep is throwing a PO301 code for a cylinder 1 misfire, and I can definitely feel it. Engine’s shaking at idle, and acceleration is rough. I already replaced the spark plug, but the code’s still there. Could it be the coil pack or fuel injector? What should I check next? Don’t want this to turn into a bigger problem
