so every now and again, I get a little blip, usually when the below things are happening
Not all the time, but number 2 seems more often

1> cruising at around 100, then floor it to change lanes
2> when stopped at lights at an idle

NOT all the time, sorry, have not pulled any codes.
Feels a lot like when a coil pack was going.
I changed the plugs all out a few months ago, but didnt do the coil packs
under guarantee so had them done as they went

Last time they went the engine light came on, so not sure "IF" going

Garage is jammed up with stuff and negative temps is hindering me wanting to go out.

So just thought I'd throw it out there

BTTT

So a bit more info,

* Hesitation/jerk only happens after cruising at say 100, and then dropping the gas to say overtake
* Pulled the codes , a lot of them, but nothing really related, and nothing to say a faulty coil pack

This really feels like that, but no codes, like I had last time, could a coil pack be iffy, but not show a code ?

Also sitting at idle and revving, NO hesitation. last coil pack when it went did have a misfire at idle revving

I can post the codes

txs again

***resolved***

Managed to get it to generate a code, by riding through the misfire, got the CEL and code, was 29d2 combustion cylinder 6

replaced the coil pack and plug, plug was fouled up, also kept it over night on the new plug to see if any leaks from the injector,
clean as a whistle, also the plugs opened nicely, since my last plug change about 3-4 months ago.
no anti-seize, but a small drop of oil

Oh without swapping the packs and just replacing the plug, there was a bit of "moisture" on the plug on the original coil.
New coil no moisture

had all the tools from last time, easy enough job, 30 minutes
