Hey everyone, I was just poking around in the engine bay of the wagon, looking through the book etc looking for solutions to an odd problem the engine has. It starts up fine, pull the choke out a bit if it's cold, warms up, choke in no problem. But after it had warmed up, I was poking around and flipped the lever on the air filter intake (winter/summer) to see what would happen. Well the engine stumbled and coughed and almost stalled. I flipped it back but it stayed rough, I had to pull the choke out again. Loosening the centre wingnut on the air filter case fixes the problem
I decided to check the emission control system, first the PCV. You can see in the pics that the hose end is covered in oil, is this normal? once I got it out the rattled which the book says means its working but I've heard that's not a valid test anymore? also the intake manifold end was covered in carbon (a bit blurry in the pic)
One other thing, I went to check the ECS canister, and it's not there!

The book says front left hand side of the engine bay, the pic I took is almost the same as the one in the book, but there's no canister! I looked everywhere but couldn't find the bloody thing. I'm sure this is a total noob observation but there's nothing in the book about it being exclusive to some models or anything like that.
Oh well if you've managed to read that essay and get the questions out of it, any suggestions would be appreciated. Pics below
The oily PCV in place
Blurry but you can see the carbon
Wheres the ECS??
Oops I should have said I know the emission control system wouldn't be causing the air filter/carburettor problem, but I was just checking it today
