Skoda Octavia - Extremely High Idle - Piet
Hi
I have a W-reg Skoda Octavia 1.6 petrol and occasionally (about once a month) the engine starts reving at 4500 revs. It can happen whilst stationary or driving. Whilst driving you realise what is happening quite quickly since the car doesn't race away from you, and you have to pulling in, stop the engine and restart and then everything is fine again for about another month. It is very intermittant but has happen 4 times. It definitely feels at if the idle speed has been reset to 4500 revs since if you have the car out of gear or the clutch depressed is doesn't go beyond that.

Any ideas? There doesn't seem to be a problem with the throttle cable. Restarting the car sorts the problem straight away.

Thanks
Peter

I was very interested to read your message as I too have a W reg Skoda Octavia 1.6 petrol, which has just started behaving in a similar manner - first it loses power and then after a couple of seconds starts racing at about 3500 revs even when parked. It has happened five times at about 2-week intervals. I wonder has anyone else had a similar problem, and did you find a cure, as I have had the throttle cable replaced and the diagnostic computer on it, but my dealer cannot find the fault. Any suggestions welcome.

There may be a VAG specific reason in your cases, but I had a problem like this with my Vectra GSi V6 Estate. The problem was the throttle butterfly having become gummy (along with the throttle bore, also gummy) causing it to stay slightly (very slightly) open. Revs in my case were about 2500RPM.

The friendly and efficient Vauxhall dealer I used fixed it FOC in about half an hour with some TLC and "carburettor" cleaner.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
