It's not advised to drive your car while it's experiencing misfires, even when those happen momentarily. You may be starting your car to go to work or driving in the middle of nowhere when your car's engine happens to fail you. If a misfire happens once, it's best not to ignore it. Otherwise, your engine power will decrease, and your car will be consuming more fuel than usual. In addition, as misfires continue to happen, vital parts of your vehicle will deteriorate faster. Hence, it only makes sense to service your car and save money in the long run.
