I believe it may just be generic code says you have a misfire. I am thinking it is likely one cylinder - one coil pack bad. Is it running rough? Try disconnecting one coil pack at a time and see if the idle changes (gets worse). That would be the bad one

Yes it is running very rough. Going to disconnect coil packs see what happens.

Don't drive it or run it too long in that condition as it is dumping a lot of fuel into the exhaust system and can damage the Catalytic conv

^ correction. When you pull the fuel injection connector and the idle changes that means the coil pack is good, not bad.

It's when you pull the connector and the idle doesn't change that means that coil is bad bc that coil is not contributing to the firing of the engine, so no change in idling.

That's what Marc meant.

So it sounds like you have two bad coil packs. I think last time I bought one they were about $50 at Advance auto.
Edit-- just looked real quick and they have them for $44ea. And if you order online there is a 15% off code on $50 or more. I carry an extra one in my trunk

I would go oem or else you might run into problems down the road.

Personally I would rather go used oem than go aftermarket part on this one. .02

Just curious, have you had the coils out recently for spark plug change? The coils are kind of fragile it seems and if not handled with kid gloves you can damage them

I am also usually oem myself on most items engine related. But I will say I have a few of the Carquest coils on mine and they have been good for about the last 50k miles

Before I bought the car from my Auntie, she had the Timing belt and water pump changed. She had a tune up done around March that included the coils....they came from O'Riley. They actually have a life time warranty on them.

FYI OP

Your current diagnosis is not definitive yet that it's the coil packs that's defective.

Mathematically it still can be a defective spark plug(s). Just keep that in mind.

However, you can confirm by swapping the suspected bad coil with a known good coil pack.

Another thing, use oem ngk spark plugs only.
