They can be caused by a variety of problems, often something to do with the spark plug. Usually an engine can run okay with a minor misfire, but if it&#8217;s bad enough, it can actually lead to catalytic converter failure, which is an expensive repair. Usually the check engine light will flash if there&#8217;s a misfire this bad.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2021\/02\/2021_02_08_01.jpg\"><img decoding=\"async\" src=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2021\/02\/2021_02_08_01.jpg?w=800\" alt=\"\" class=\"wp-image-5336\" \/><\/a><\/figure>\n\n\n\n<!--more-->\n\n\n\n<p class=\"wp-block-paragraph\">This Honda Odyssey came into the shop with a very bad misfire. You can usually hear a bad misfire in the sound of the engine or feel a vibration, but this was even easier to hear than most. One of the spark plugs had actually melted and come loose from the cylinder head. When there&#8217;s an open hole into a cylinder of a running engine, it&#8217;s very loud.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2021\/02\/2021_02_08_02.jpg\"><img decoding=\"async\" src=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2021\/02\/2021_02_08_02.jpg?w=800\" alt=\"\" class=\"wp-image-5337\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Not surprisingly, not only did the spark plug melt, but so did the ignition coil. A non-melted coil is on the right. I don&#8217;t know what was causing such a bad misfire, but melting a spark plug is impressive. I&#8217;ve seen a plug or two pull out the threads and blow out of the hole before, but they weren&#8217;t melted like this. As you might expect with the plug melted like this, the cylinder head was also destroyed, so the engine would need at least a cylinder head.<\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\" \/>\n\n\n\n<p class=\"wp-block-paragraph\">New blog posts every Monday and Thursday, plus pictures throughout the week on <a href=\"http:\/\/facebook.com\/mechanicalmalarkey\" target=\"_blank\" rel=\"noreferrer noopener\">Facebook<\/a>, <a href=\"http:\/\/twitter.com\/mech_malarkey\" target=\"_blank\" rel=\"noreferrer noopener\">Twitter<\/a>, and <a href=\"http:\/\/instagram.com\/mechanicalmalarkey\">Instagram<\/a>!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.youtube.com\/channel\/UCasCW0ImD3UuLeMu5RAZCXg\" target=\"_blank\" rel=\"noreferrer noopener\">Watch Mechanical Malarkey on YouTube!<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mechanical Malarkey <a href=\"https:\/\/mechanicalmalarkey.com\/merchandise\/\" target=\"_blank\" rel=\"noreferrer noopener\">T-shirts, hats, and stickers<\/a> are available to order!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">-Dan<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Misfires are probably one of the more common engine problems.
