Misfire in the third cylinder, everything been fixed why is it still reading misfire the third something

Hello, replacing all the parts you think are a concern is one way to attack a problem, and I get it -- in many cases, this will resolve it. But what needs to happen is testing of the engine to find out what the source of the misfire actually is. Has a compression test of the base engine been performed? What are the pressures for each cylinder? Is number 3 low? If so, has a leak down test been performed? There's also a slim chance that parts you have installed are not working properly - even if that's unusual. You can always swap a coil for another cylinder and a plug for a different cylinder to see if the misfire chases either of those components. Hands on testing will lead you to where you need to focus attention. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
