Golf IV GTI 2.0 idling problem - alibaba
Has anyone experienced idling problems after a restart when engine is warm on Golf GTI with APK 2.0 litre 8v engine? If the car is up to operating temperature and then switched off and left for about 5 to 15 minutes, on restarting the engine (throttle not touched) speed immediately goes up to 2,000 to 3,000 revs and then slowly (5 to 10 seconds) goes back to normal idle speed. Occasionally fault happens after warm restart when engine has idled normally initially, but then idle speed goes up in first few hundred yards(noticeable between gear changes and a bit disconcerting!). This does not happen for an immediate re-start when warm, nor does it happen if the engine is warm but left for half an hour or so. Any suggestions as to what the problem is please; car nearly 3 years and 15k miles old?
