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
