Hi guys, my car has picked up a fault. I have the ABS sensor and traction control light on. The issue is that it revs itself when sat at juntions. I sound like a right knob! the throttle just keeps picking up revving between 1500 and 2000 rpm.

anyone had this before?

nut and bolt rebuild on everything except the engine!

My first thought was a throttle position sensor of some kind

Remove the surface corrosion on the pins { male and female ) of the 90 pin ECU connector with a good switch cleaner such as Servisol Super 10.

Works 95% of fhe time, hardware fails are rare.

Gave that a go, didn't work. I have it booked in to a Renault specialist this week so see what they say.

Repeat the procedure with the large white connector R255 under the fuses & relays in the engine bay fuse box.
Also the throttle body and throttle pedal plugs.
