This issue just started creeping up recently. Car runs fine otherwise.
When fully warmed up and usually when sitting in traffic, the car will start to run lean according to my wideband and then. It will idle at 13.8-14.4 on the wideband and then suddenly hit 17.1 and actually have a slight smell of fuel. I'm wondering if something is getting heat soaked and starting to malfunction.
BLMs when this happened were at 129 and the narrow band O2 was reading 068 for a while until I blipped the throttle.
Fuel pump is a two year old Racetronix 340 with hotwire, new injectors. Charging system is all good too with anew battery and alternator.
Any ideas of where to look?
