My check engine light keeps flashing (No codes stay) which means I’m misfiring. I ran into this earlier in April and took my car to the stealer ship. They saw that my stock spark plug wires had melted in certain points due to the heat of my aftermarket headers. So I replaced all of the wires with new Magnecor ignition wires (& also added Kool Socks). This fixed the initial problem. Now my car is misfiring again and I can’t figure out why. I took out all my Magnecor wires and reinstalled them again just to make sure they were all secure but she is still misfiring. After the car cools the misfiring seems to go away but the second it heats up it comes right back.

Anyone have any ideas as to what else could be causing me to misfire? Any help would be great.

I hate to state the obvious about checking the plugs. Inspect around the engine in the dark with it running to see if you see any arcing. Just because the wires aren't melted, doesn't mean they are good.

Replace the plugs. You could have a hairline crack which you can't see.

I just checked that and couldn't see any arcing in the wires...

Ground wires? Can anyone find the link for this?

So bad a bad spark plug could also be the problem?
