"Hi Recardo,

Based on what you've explained, to me it sounds like you may have a worn-out spark plug, ignition wires, or a vacuum leak somewhere in your vehicle. I would inspect cylinder #4's spark plug and wiring for any physical damage. Try a replacement spark plug to see if that fixes the problem. If not, I would recommend taking it to your mechanic for further investigation.

Best of Luck,

Drew."
