Greetings experts,
I need your advice on a 997, 2007 C4s mileage (160000kms)...
Car hesitates at idle only at around 1000 rpm, than it is smooth( please check video link) it happens only while I kickdown(i rapidly pressing accelerator)... Although if I accelerate smoothly there is no hesitation.......there is also some strange smell with very little white smoke at exhaust as well..
I found some oil in all the spark plugs, car is not turbo, I suspect it could be oil separator. But I don't know how to be sure that it is the oil separator that is causing oil inside the cylinders...
Car is low on power as well, spark plugs+ coils+ air filter are brand new original...
I am uploading a link to the video below for reference..

Get a code reader and find out what all the blinking warning lights mean to start with. It's possible you have a major vacuum leak and that's why the ABS light I on as you can't build vacuum for the brake booster. The vacuum leak could also be caused by a failed AOS.

The abs light is there because we tried disconnecting battery & some lights came on, otherwise no codes for abs..
Thanks
