Posted before about my Megane over revving when accelerating over say 3,000. Fault codes were showing faults on throttle track ok 1 and 2,this was diagnosed by RAC when i called them out.
Replacing accelerator with the potentiometer on it made a huge difference, accelerated perfectly!
But, 7 days later started car and check ignition light and no accelerator reaction and high revs at idle.
Rac guy said throttle pedal or throttle body, so yesterday stuck on new throttle body and also unplugged every wiring connector on ecu etc and cleaned with contact cleaner.
Car starts, runs fine except this over revving stil when pushing on a bit.
Never been a change in clutch pedal feel,bite point etc, no jerking, or noises in clutch operation, no burning smells, car pulld away at 20mph in 4th and 5th gear with no over revving?
I'm just unwilling to accept it's really the clutch, i've driven a car and a motorcycle with a slipping clutch, but they slipped all the time, my car the revs are more erratic and less consistent accelerating?

Take it to someone who knows what they are doing.

Had car to a French car specialist and he also thought the two fault codes were behind it. He tested car accelerating in 5th gear like i did and it accelerated and held up, just took it's time obviously being in 5th gear.
It's the fact it's fine sometimes?The day before the car was diagnosed with the two fault codes car was fine!

Diagnosing a slipping clutch is only slightly more difficult than sitting upright, you're the person behind the wheel so if you're incapable then take it to someone who is.

As i said, French car specialist nearby drove the car and it pulled away perfectly from 20mph in 4th and 5th.
It's the inconsistency that's confusing me, and the garage. Car was fine, then two throttle fault codes, then revs all over the shop.
Like today for instance, car is pulling fine.

Your clutch isn't slipping.

Sort your throttle out.

Diagnosis over the internet isn't easy.
