I just purchased a 1996 960, it has 178k on it.. WIll this be a good car? Also when starting it I hear some sort of motor running like an air pump or load leveler I have heard in other cars, by the end of my street I hear this hum slow to silent. I am having the cam shaft sensor in the A bank replaced since it keeps shutting the car down around 2500 Rpms, we are also having the T belt replaced and water pump. Would it also be wise to run an engine de-gunker prior to an oil change? If anyone could address these issues it would be appreciated!
