P1152 Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2
Did you plug in your two upstream sensors? Check HEGO sensor fuses and wiring
The computer is not seeing them
do you have OBD2 scanner?
Knocking ticking from pass side:
Is it exhaust tick? (look for black soot around where sound is coming from inspect exhaust with flashlight)
not uncommon with new manifold/downpipe engine installations
Or is it a new lifter that needs to pump up? (valve train noise)
