I Have a 1997 1.6 GL Golf (AFT Engine) . I am having a few problems with poor idle and erratic revs - i.e when you start the car the revs shoot right up and then come down again after a few seconds. I want to clean the throttle body to see if this makes a difference but was wondering if the TB can be reset any other way other than using VAG-COM, any advice would be appreciated.

Thanks
