Engine running rough and service engine light on.Error code says that Cylinder #5 was misfiring. What should I do to fix this?

If it has over 100,000 miles on it do a complete tune up. If it's not due for a tune up check the spark plug and spark plug wire on cylinder 5. If all is ok there then compression test cylinder 5. You should get a reading of about 150psi or higher. HTH. -Jim
