Morning, so just over a month ago I shot a plug and took it in to have a helicoil installed and replaced all 8 plugs and coils at the same time. Just a few days ago I shot a different plug, yet again I had a helicoil installed with another new coil and plug. As it stands, it’s still misfiring and so I replaced the Ignition terminal connector to be safe and was running fine for about 3 different 5+/- mile round trips and then the last start up, back to throwing a code and running a tad rough. Any ideas?

Do the misfire codes correlate with the cylinders you had helicoiled? Not sure if your mod motor has Cops or coil packs-but maybe swap the cops around and see if the misfire follows, or switch the plug wire with a different plug wire if so equipped .

I actually happen to get it all figured out today, connector was loose and the shop replaced the wrong one so I’ve got another one ordered and won’t drive it til it’s put in but thank you.
