My 2005 Hyundai sonata's third cylinder is misfiring.
I have replaced spark plugs and wires, and replaced ONE of two coils. I do not know the order, left to right or right to left, that the cylinders are numbered... I do not know if I just got a coil that happened to be a dud? maybe a bad wire plug? perhaps some debris fell inside the 3 cylinder plug hole. I have no idea... please help. It is running on decreased power, runs rough, idles rough. I also had the idler cleaned off. THANKS!
sounds like the firing order is off. use google to find the correct firing order
Firing order is 1-2-3-4.
