So my check engine light came on, then a rough idle, check engine light started to blink and then stopped blinking. Light stayed on. I changed out the all the spark plugs and wires. Made sure everything was tight and good to go. Turned the truck back on, let it sit for a min or two and then the rough idle and flashing engine light came on again!!!! What to do next????
S.O.S. misfire/catalytic converter???
