cat blocked, or you have misfires where fuel not being burnt in cylinders,, i had this on a prince engine 1,6vti and was due to inlet camshaft vvt spring fingers had fallen out of rear of the cam followers and caused the valves not to open enough and cause a over fuel issue and not enough air,
Just cut the cat off and still glowing going to check the timing and if there are any air leaks on the supercharger 👍
How’s the fueling/timing? Could be over fueling like crazy.
Just took all the throttle body and everything off as the cat was clear and the map sensor vacuum pipe wasn’t connected into the push fit properly would that have caused it
when engine leans out will cause that when fuel to air to pushed out side spectrum ,, if your running smaller ss pulley and that fault would do it even more so.
