Hi guys.
When I start my car, it idles at about 600 rpm, and gives a bit of a shake to a car. When i switch off overdrive, it resumes back to normal for some time, but starts to drop after about 5 mins
Anyone can advice, what would be the reason for this to happen?
Bought this car just today, so dont know much about it.
It is a R34 GT,1998
Thanks
