Yeah from my experience thats what I thought. My L wagon melted the cat and the exhaust note changed from "dub dub dub dub' to " ahhhhhhhhhhhhh'
Low revs were fine but as I pushed past 4000rpm it just died in the arse
I'll gut the old oxygen sensor and put a hose nipple in it to test the exhaust pressure for peace of mind.
I checked the left hand intake OCV screen (because it was the easiest to remove) and it wasnt there. Is it safe to assume that all the screens have been removed?
