What is the normal outcome when the 2003 Volvo S 60 gives reduced engine performance code and the idle jumps?

Hi

I am assuming it is a petrol engine. I experianced the idle fluctuations / surge and cleaned the trottle body with carburetor cleaner or trottle body cleaner.

On the top of the intake manifold (front of engine) there is a +- 8mm rubber pipe (almost in the centre). Remove clamp and pipe when engine is at normal operating temperature and spray about 80ml into manifold via connector of the rubber pipe. Replace pipe and start. Staring would be difficult and smoke will appear from the exhaust. Drive vehicle and repeat cleaning procedure.
