Hi guys, hoping someone can assist or have some knowledge on an issue i'm having...
2 days ago the car started with the issue, idle fluctuating between 1500rpm & 2000rpm
The vehicle is also over-fueling quite badly now... i have tried to locate any vacuum leaks and honestly cannot find anything, should i try the idle control valve or AFM... could injectors do this? Fuel pump?
When driving and if you let go of the accelerator while car is in motion, you can feel it do the same thing.
I've uploaded the video to youtube, link below :
I will get the car scanned on the weekend to check if it's anything else.

Any advice would be highly appreciated.

My experience with a vacuum leak was more like the car was hunting, that rev range seems very specific.

Did you manage to find the fault and get it sorted?
