Feels like misfire but i really dont know

Just got my s3 back from having a whole new clutch fitted. 1st 2nd n 3rd feel great but rest of gears on full boost 1.5 are generating a miss fire of sum discription. This only happens when i floor it. If i floor it n release some of the pressure it seems fine and its not coming up with no fault codes which is really weird. Plus shes bin stood for about 5 months before the clutch was fitted i really need help with this as i wont her running sweet and sound again

It might be the 5 month old fuel has lost some of its 'zip'. Have you tried a tank of super-unleaded?

No havent tried that stuck 30 quid of normal before i drove from manchester to north yorkshire had it in 5th nearing the end of my journey and the misfire prob started to happen more on full boost each time it happend i had to let of the loud pedal as i dont want a huge bill again and leave her locked up again

There could be a buildup of water in the tank. if you've still got plenty of the normal left, put a bottle of Redex in and see if that helps.

If i have water in the tank then surely ill have to drain the tank? Thought redrx only cleared blocked injectors but still wont harm it though lol

if there's enough, yes! this test may help to confirm if it's a fuel contamination issue though.
