I have 2005 nissan altima and when i start it, it shakes and then stops after about 2 minutes and my service engine soon lite came on. I took it to auto zone for a free diagnostic check and they told me the 3rd cylinder was misfiring do you think i need to change the spark plug on that cylinder or just get a full tune up all together.
