[HELP] B48 Running rough, rich mixture..
Hi,
I have a 2016 BMW 430i GC, it has around 98,000 km and is currently BM3 Stage 2 with a sports-cat, 435i exhaust, aluminum chargepipe+inlet and NGK sparkplugs. I only use 100RON fuel (US 93oct). I change oil (5W-30 Castrol M) every 8k km and sparkplugs every 2nd oil change. The car has been running pretty rough for the past few weeks, on cold start the idle hesitates a lot and sometimes the car even stalls. I let the car idle for 30s before going into gear, however, it drops revs like crazy when I select Drive/Reverse. I have also noticed that the tailpipes are quite black.. I have included a WOT log below and also the error codes I got today along with a CEL.. I am suspecting a leaky injector or failing HPFP? I appreciate any input. Thanks!
