Last night my hyundai accent '01 1.6dohc (80,000mi)check engine light started blinking. I checked the codes and I got 0507 0300 0301 0302 0303 0304
(higher than expected idle, random misfires and each cylinders misfires)
I changed the plugs and wires today and there is no change in the codes or the really rough idle, moving the engine sounds fine until I take my foot off of the gas, do you think replacing the ignition coil will fix this.
any help will be appreciated
