If fed a lower ron fuel, the ECU will <beep> the timing and it will feel slower.
When back to normal 98-99 RON stuff, you should give it plenty of hard runs so that it re-adjusts. If it is still running badly, get it checked.
How "dodgy" was the fuel you used? You didn't use diesel did you?

I had a bad week after filling up with "premium 98" from the Tesco at Bicester. Cold starting was poor (often took 2 attempts, and running was rough and noticeably down on power.
A few tanks of V-Power, after letting the tank run almost dry (try carrying a can of V-Power with you and letting it actually run dry) sorted it out though.
