“Why does the engine of JMC New Boarding sometimes stall o r misfire at idle o r low speed?”

On certain drives o r at idle, the engine seems to run roughly, shakes slightly o r misfires, and occasionally stalls — even though spark plugs and battery seem fine. Could a bad ignition coil / ignition module o r wiring fault be the cause? What should be checked to isolate ignition‑system faults vs. fuel o r sensor problems?
