All stock glanza having this problem with running rich on idle and fine on part throttle and cruising.
Idles fine, starts at 1200rpm when cold and then moves down to 800-900rpm but lambda sensor reads 0.8 - 0.9v. At cruising and part throttle reads 0.3 - 0.8v which I think is fine.
Checked TPS voltages at Ecu pinouts
PSW - 5v on idle and part throttle
PSW - Ov on WOT
VCC always 5v
IDLE - 0v on idle
IDLE - 12v on part throttle and WOT (maybe floating voltage?)
Map sensor 2.6v with engine off
IAT 0.8v with engine off
Coolant sensor 0.4v (car has been resting for 20min)
Looking up resistance tables for tempreture sensors, iat and coolant sensor seem fine.

New to here and need some help.

What could be the issue please? Thanks
