Brett West Posted August 3, 2013 Report Share Posted August 3, 2013 Hi. Idle was fine. But then changed the fuel pump, pressure regulator and injectors. (Sard 800cc.) Got everything else pretty much sorted but idle. When the engine is warmed up idle starts to swing and so does the afr. Things that smooth´s it out little is when i take the closed loop lambda off or make it run rich. i.e changing the fuel table or turning on a/c. Have tryed changing the idle base positions and they don´t seem to do much difference. Nor changing the gain tables. Could i have vacuum leaks or something? Or could it be some sort ignition problem? (Haven´t touched the ignition times after the upgraded fuel components. Car was running smooth idle before upgrade.) Suggestions? Quote Link to comment Share on other sites More sharing options...
lemmy01 Posted August 4, 2013 Report Share Posted August 4, 2013 Try the idle ignition trim feature. Quote Link to comment Share on other sites More sharing options...
