Astra 1.6T Engine Idle Problems

Hi Guys,
Sorry for typing in English. I'm from South Africa and have a problem with my car.

when My car is Warm my car Idles rough and it feels like the car is swallowing and vibrating. Does anyone else have this ?

you can reply in German, I will understand

thanks for your reply

This mainly happens when the car has reached operating temperature. I feel a shudder under my seat every 2 or 3 seconds. The rev limiter does move but not too much, slight up and down. Other times it feels as if the car is vibrating when it Idles. When I stand by the exhaust it sounds like a misfire and when looking at the engine I can see the slight vibrations/ shudder. I have seen that other people on the forum has also experienced this but i just want to make sure it is normal. I do agree with you that when the Car idles it runs lean to reduce emissions etc.

I took it to the dealership a few times and they can't dind anything wrong with it

I recently changed my oil to Dexos 1 gen 2. The noise at the exhaust isn't really a misfire, it's more of "hollowing" sound, It might be the car running lean to save fuel. We don't have 98 Ron in South Africa, Only 95 Ron. I've always used 95. The Manual does say that 95 is possible but that 98 is preferred.

Hi Guys.

Does anyone on the forum have an engine vibration when their Astra is Idling...it alsmost seems like every second the car has a "jitter" or shake...this is the 1.6T
