Hi all, i have a 2015 auris 1.2t, had it from new and been a great car, but for the past year or so its started to idle poorly, when coming to a stop it drops rapidly to 500rpm then goes back up to around 600 rpm, it judders like its missing, been in to toyota who cant find anything wrong.
Ive changed the plugs, coil packs, gave it a service, which i do regularly but still no better, tried to reprogram the throttle body but no joy.
Any suggestions would be great
Thanks all
