Car missing jerks and has lost power

[05 vz]

Car is a 05 vz executive automatic 3.6l so I went to drive today and I now have a massive miss at idle and on acceleration the car jerks really rough and has hardly any power any ideas I'm not very mechanical minded / handy at Machanical stuff but what I've read on google keeps coming back to saying bad coil pack? So should I replace all my coils I found a set new on eBay for 60$ and if I am to replace them good idea to get fresh plugs in at the same time? Thanks

As you're not mechanically minded it would be best to take it to a mechanic and get them to look at it for you.

A $60 set of coils will be junk unfortunately...

How do I unclip the coils been told to disconnect one at a time to test each coil to see if one of them is rooted so I had a look but don't understand how to unclip them to test. The 60$ set of coils is acdelco brand

Undo safety tag and push down on release.
