My fabia has started playing up when I'm changing from 4th gear to 5th about 2/2500rpm and 5th to 6th as soon as I put my foot on clutch to change gear the revs go shooting up , my foots not on the accelerator so unsure what's causing this , has anyone got any ideas ? Thinking a sensor fault if throttle pedal sticking but it's only going into 5th and 6th gear . Cheers

Mines just started this. Did you find a solution?

 

I'm thinking it may be a sticky throttle or abs sensor or the loom cables.
