Faulty accelerator from cold !

[Mark_W]

I have a fault with my accelerator, in a morning and only from cold if i try to sit at any speed i can fell the car lunging forward then easing off over and over etc within 1-2mph, but with my foot completley still trying to sit at a steady speed . . . after around 4-500m of trying to keep it steady it then kicks in and does exactly what i want it to but it does it every time its cold and its starting to get very annoying, is it going to be a faulty accelerator, with it being on a drive by wire rather than (a preferred) cable ?

It's not a faulty anything. It's the cold map the engine runs on initially.

All RS Clios do it, even my 200 does it. You'll get used to it. Besides, you shouldn't be flooring it from cold anyway.

well i think thats quite erm, french tbh and very annoying knowing that im just to live with it ! And i dont recall saying i do floor it when cold, if anything its the only rule i live by even though im a mechanic by trade, if i do damage to it i can only fix it myself anyway

They are all the same.

Cold start emissions regs apparently mean its mapped like that but yes, all unmapped renaultsports do it.

 

[Mark_W]

so in theory to get rid it wants mapping ? Whats the best map to go for these days for a 182 ?

 

[Dankata]

The same as it always has been always will be... a live map...

Without bothering to search, Doesnt the 98Ron map on the RS Tuner sort the cold start issues out?

 

[Riley!]

Rs tuner does sort it out yes, cheapest option and a few more MPG. Worth every penny, best mod I did on my 172 all day long.

RSTuner stops it being AS lumpy on cold start by raising the idle speed, but it's still lumpy and you'll still get this lack of acceleration - it's normal and as said already you shouldn't be accelerating over 3k when cold anyway.

As said RStuner helps but doesn't eliminate it! clean the throttle body also.

 

[richd]

mine does this too lol

 

[Mark_W]

Will try having a clean on the TB tomorrow and then look into a map at some stage or even the RStuner and to be honest addicted youre the same as christopher, i dont recall saying i do 'floor' it or even go over 3k when cold, takes a lot for me to do so when warm and out in open roads let alone firing it up and nailing it straight away its just a simple little problem i thought may have a cure to get rid of
