Could this be coil symptom?

I have an 04' CS that seems to 'shudder' sometimes when accelerating in 5th or 6th gear. Feels like it's in too high of gear and I usually just downshift with the tip to remedy. Mostly notice this when it's warm and been driving a while. No other issues with idle or anything. Could this be faulty coil symptom?

Sounds like the same thing I had on my 04 CS. Turned out to be the coils and replaced under warranty. Have them check the coils for cracks.

Yup, sounds like coil.

I also had unusual vibration after turn on the ignition, which was a sign of the cracked coils.

shuddering

Replaced all coils/plugs. Still did it, dealer then replaced the left fuel pump, cured it.
