#1: rough idle and nearly cuts oot Author: chefboy1985, Location: newcastlePosted: Mon Aug 11, 2014 9:08 am ---- All yesterday car was fine until I was driving back hme and pulled up to a roundabout and the car was nearly stalling,thot was a one off as when I got up to motorway speed again it ran fine.stop outside my house and let it idle it was running rough as hell!!!anyone had the same problem?it's a 2005 206 gti,it's was also really heavy rain last night so not sure if that could have anything to do with it?
I am cleaning the throttle body and sensors to c if that will help.

** Just realised it's 2005 and I know nothing about GTi engine's - but think the later ones aren't cable operated?
But I'm presuming it still has a stepper motor and air bypass in a similar manner....?
#6: Re: rough idle and nearly cuts oot Author: chefboy1985, Location: newcastlePosted: Mon Aug 11, 2014 11:10 am ---- I have cleaned all that out but still the same am stumped!!the car is also decated but was running fine and when I tried to c if there was any faults cumin up using my torque app apart from the usual one because there is no cat.goin to use the fuel that in it then put vpower back in,as I says before it's the only thing I have dne different.

#10: Re: rough idle and nearly cuts oot Author: Danw_VVT, Location: Herts/LondonPosted: Wed Aug 13, 2014 2:08 am ---- Bit late but it had the same issues with my 206 1.4 sport
Turned out mine was because I had a decat system and the post cat lambda was sending signals say the car was running to rich so obviously reducing the amount of fuel the car ran.
Unfortunately mine was all the time and even using the resistor trick didn't work also tried a sports car system and nothing cured it
