Hi guys,I am having a problem with my engine and can't figure out what the problem is. After driving for a short period the short term fuel trim goes to +25% and then a short while later -25% before settling down to around zero plus and minus around 1.6%. The Long Term fuel trim permanently sits at -0.8% and my idle is normally steady at 640rpm.When I come to a stop and the fuel trim goes through the roof the idle bounces up and down and sits at around 900 rpm. Anybody have any ideas about what could be causing this?
