wrong spark plugs
I have a 2012 sxt avenger 2.4 L 4 Cyl. I've had it for two months and bought it with 63330 miles on it at a supposedly reputable car dealership. A week ago the check engine light came on which it had never done before. About five miles later the car was shaking so bad it was undrivable and had to be towed to a repair shop. They said there was two pending codes on cylinder 4 and 1 saying that they were misfiring. The shop looked at my spark plugs and showed me thay all four had lost their tips and only remained functional, additionally they had infusedunto into the threads and each o needs to be rethreaded. Then the shop found that the spark plugs in the car were .25 inches too long and nothing like the required style of spark plug.
What would this do to my engine
What's the normal service interval for spark plugs
What is part number of spark plugs fo 2012 sxt avenger?
