Need to change spark plugs but also need to find out why this is causing them to go bad over advanced ignition, timing, poor engine cooling
system efficiency (scale, stoppages, low level), a very lean
air/fuel mixture, or a leaking intake manifold. When these
conditions prevail, even a plug of the correct heat range will
overheat. Could be the poor engine coolant or leaking intake manifold. Might have to put it on a machine to diagnose the problem.
