I've started getting a jerking /twitch form the engine on startup and today while driving it became worse

When putting load on the engine. The check engine light was coming on then going again.. I picked up three new coils as I knew previous owner changed only three 10k ago.

After I changed them the engine light came on permanently and the engine is still twitching/jerking

I'm getting a code reader on it tomorrow but are there any other things that would give same symptoms?

It's an 05 V6. Any other hints to what I should look at are more then welcome.. I keep ending back at the coils..maybe sparkplugs also..

Got hooked up with code reader today.indeed coils.. Had multiple misfires logged.

Pulled three bad coils. None really showed signs of cracks or noticeable wear.

Replaced all sparkplugs and coils.. Purrs like a kitten...and like new.
