Re: #5 cylinder not firing - what are my options?
Many things can cause a cylinder to not fire, especially at idle. As stated above, pull the plug on #5 and see what you got. If it is oil-free, it should not take much to get it going again. Check for vacuum leaks , such as a bad gasket or maybe a vacuum hose on the #5 runner that is leaking. Swapping the plug and wires is certainly a cheap and effective way to start.
