G60rob 0 Posted September 25, 2007 Starts OK, idles at 1000 rpm from cold then drops to 800 when warmed up, so all as normal, mostly. But on long trips when it's thoroughly hot it sometimes idles at about 1000 rpm, and lumpy. Not a big problem, yet, but I'd like to get it sorted in case it develops into something worse. I've searched the idling threads, but most problems seem to be stalling/ rough running/ slow idle. Anybody know what this is? Quote Share this post Link to post Share on other sites

Pickard1 0 Posted September 25, 2007 You could try the idle screw at the back of the inlet manifold. These can work loose over time and eventually pop out as they have an integral o ring that gets old and worn out. It could be loosing its seal as the engine gets warm. Is there any whistling noise?

G60rob 0 Posted September 25, 2007 No whistling that I've noticed, but I'll listen out for it. Quote Share this post Link to post Share on other sites
