If the MIL was on and there was a fuel-trim code; then you have a fault. [Cleaning the oxygen sensor is pointless......!]

A small air leak is one possibility; TB may be along later and know the likeliest spots to look on this model.

Not sure if I can be of help but my 02 1.8 behaved like that when I first had it. I put it down to my ham footed clutch control on, at that time, an unfamiliar car. It only happened a handful of times in my first few weeks of ownership, then it stopped happening and, touch wood, the prob has not recurred.
Please be assured I'm not casting any aspersions on your driving Dougie, just recounting a similar experience and the outcome.
Good luck in sorting it.
