Megane 2004 1.6vvt
I have a problem with the throttle,when changing gear mostly from 1st to 2nd the throttle has a mind of it's own and can rev itself up to 3500rpm! also when idling the revs can stick around 1100rpm for around 20 seconds before dropping back to normal idle speed 800rpm.
The throttle housing is as clean as a whistle so it's not sticking.
Could it be the fly by wire system?
Cheers

Re: throttle problem
Some others in the forum will no doubt give their input which will be a lot more valuable than mine but I think it sounds more like a ignition coil problem and there is a misfire in one of the cylinders. If it's not that I would be thinking about dephaser or a sensor but I think ignition coil and misfire is most likely.

Re: throttle problem
cheers John,the dephaser was replaced a couple of years ago which I thought ruled that out,however the engine sometimes doesn't start first time.
have changed plugs,camshaft sensor and crankshaft sensor,maybe the coils need replacing.
Hopefully the dephaser doesn't need doing again!

Re: throttle problem
If you aren't getting any codes, the engine could be being commanded to rev as it does, in which case the throttle pedal sensor may be kaput.

Best advice for Megane owners: sell it before it bankrupts you!

Re: throttle problem
cheers,that was the only thing left to check.
Is there any way of checking the sensor on the pedal or is it a case of replacing the whole throttle pedal assembly?
