Advice please re stiff accelerator

[Cruiser459]

Going to use the bank holiday weekend to identify what needs doing on the 114k 02 RX I picked up yesterday.

First thing - there is an initial stiffness in the accelerator when setting off so can see this could be tricky in traffic. Have to press the pedal quite firmly, nothing at first, and then car picks up smoothly but a bit jerky in traffic. (Have had an RX before so I know it's not normal)

After that point accelerator works exactly as you'd expect - it's just that first part. Car drives like a dream otherwise.

Can someone advise where/what I should start looking at please!

The car had been sat for a few weeks before I picked it up and in 10 days it will be going in to my friendly independent for a health check anyway, but wondered if it was an easy obvious fix for a relative novice to do themselves over the weekend?

Thanks as always!
