I have a 2011 1.4 petrol Corsa D.
When accelerating the car lurches. This doesn't happen all the time and is seemingly random. It may happen when I accelerate from 60 on the motorway back to 70 or 30 to 40 etc. It feels like it loses power for a split second then regains power and loses it again until stabilising.
Another potential symptom is that the engine ticks. This again isn't constant but seems to happen after driving for a couple of minutes. It isn't noticeable when driving. The tick stays constant and does not change when applying any throttle (the sound just fades into the background).
No warning lights present.
Does anyone have any idea what the cause of this is? If you need any more information let me know!
