Mazda CX-5 check engine P1309 Misfire Detection Monitor
My check engine light came on my 2013 Mazda CX-5 when I started the car Sunday morning. I took it to local mechanic today who kindly did the diagnostic for free and got code P1309 Misfire Detection Monitor. He said it was a random cylinder that misfired and cleared the code. He recommended coming back if the light comes back on. Any thoughts on reasons and potential repairs for this code?
I found this with a Google search https://www.autocodes.com/p1309.html
