I tested vacuum at nipple at its steady at 22inHG so that seems good. New sensors and everything.
The EGR MAP Baro sensor reads 8inHG at idle using OBD2 scan.This sensor shouldnt affect fuel trim, correct?
Using the obd2 scan tool -
Upstream sensor fluctuates between 0.1mv and 900 mv as it should. The downstream sensor however is stuck at 0.35mv at idle. It only starts approaching 0.5mv when im driving the car for a while. Is this normal? Both 02 sensors are new.
Maybe the issue is the thornley header / custom exhaust. Maybe i should go back to stock.
I also replaced the fuel injectors. fuel pressure is spec, i tested this at the rail.
