has my cat collapsed?
Discussion
My 1.7 Puma has lately lost power, developed a rattle and has started coughing and spluttering at higher revs. When it started i had a whispy air noise, sounded a bit like a blown manifold gasket but it was alright, then the rattle started then the loss of power.
The car drives fine at lower speeds apart from the rattle but once you try and open it up the video shows what happens, sort of feels like fuel starvation.
I've had it plugged into live data to check the 02 sensors, No1 is jumping from lean to rich as normal and No2 is doing the same, which i believe it shouldn't?

If sensor 2 (post cat) is switching then the cat as failed/broken up it should flat line all things being equal, I think this sounds like the broken cat is blocking the exhaust pipe on the smaller cat outlet tube like mentioned already remove the cat and have a looksie The car drives fine at lower speeds apart from the rattle but once you try and open it up the video shows what happens, sort of feels like fuel starvation.
