Slight hesitation on constant throttle

I’ve began to notice an occasional slight hesitation from the engine while driving at a steady speed. What could this be? Car is a EU1 K series, with Emerald & TB. The obviously things to me are to work backwards from the spark plugs, to the coil.

Anything else to check? I can plug the Emerald into the laptop to see if a sensor is dud, but it seems to run OK otherwise.

Thanks in advance.

Could well be the TPS playing up.

I had in mind something like that. I know there is the function in the Emerald software to set up with the range of pedal/ throttle travel, I thought about a reset, and checking it wasn’t gunged up / cleaning the contacts.
