Q: misfire in cylinder #1

asked by on June 12, 2016

I've had this mis fire for a while now, even after replacing the spark plugs, spark plug wires, distributor cap, coil pack, and fuel injectors. And it will every once in a while idle ruff on the start or have issues not wanting to turn over, and some gas has to be given until it doesn't want to shut off.Also, every once and a while (once a week probably) it will shut off at a light or stop and sometimes while driving. It seems when the jeep warms up it runs better. Please help I don't know what else I can do to solve this. Thank you
