2007 Holden VE SV6 LY7 poor idling

[Mon-aro]

Hi guys im having poor idling when starting up the car, and black smoke coming out of the exhaust. Ive noticed few holes along the exhaust system would that be the cause? sometimes sounds like a lawn mower and when i accelerate is slow to respond? any ideas?
PS: engine light fault code p0521 ( Engine Pil Pressure Sensor)

Check out market place for a S/H exhaust,
Then get it re-scanned.

So bought a s/h exhaust midsection and replaced it along with 2x brandnew O2 sensors and still having the same issue on cold start? Please refer to the video below. the engine light is as mention for oil oressure sensor.

P0521 oil pressure sensor only.

24mm Deep socket and a new OPS will fix that.

Really? I previosuly had the same code popping up in different cars and never had those symptoms?

Always best to fix the indicated items first, get them out of the way,
Then work on the other unknow symptoms,

Side note,
Check the wiring and connector to the OPS,
being its located just above the exhaust manifold, it subject to a fair amount of heat.
