Where are the coil packs

[stateofidleness]

fellas, that might be a dumb question, but the 1128 code I get occasionally says something about misfire blah blah blah and I've seen a lot of posts recently about swapping/replacing coil packs for that bank/cylinder.

where are these coil packs and what do they look like? is there 1 per cylinder, or 1 per bank?

also, with that CEL code in mind, what would I swap to test the coil packs?

i was leaning towards a vacuum/exhaust leak (which I know i have), but thinking I might have the mechanic check these coil packs as well

The coil packs are on each spark plug located on both sides of the engine. There are six of them total with 3 per side. Search spark plug change and you'll see good pics and how to get to them.
