Ok I'm taking a shot in the dark hoping this has happened to someone else.
I have a 99 procharged cobra. Im getting p035x codes ( primary/secondary ignition coil circuit fault) I literally have codes for coils 3-8 right now. It doesn't consistently misfire. It drives fine and pulls hard 90% of the time. Usually get misfires after getting on it (ex: downshift to pass truck up shift back to 4th/5th and lightly get back on it, starts to misfire) now it will usually do it for a couple seconds and then just go away. Also usually goes away if it hit wot.
Replaced all coils with different ones already
Now a couple weeks ago I had a ground strap come loose and car died. So I was running with a bad ground for a while. Could this have fried the drivers in the PCM? It's something common with all of them that's what's confusing me.
Also spark plugs are brand new. I'm running Platinums 1 heat range cooler than stock.
I have about 3000 miles on a rebuilt motor.
