Was it doing it before you put the front mount and cone filter on?

Should be able to clean the ICV up with a bit of carb cleaner and a toothbrush.

When I had the maf issues on the wagon recently, the running improved when the maf was unplugged suggesting it was the maf according to Glenn at Carnetix,after changing the maf it then ran as it should.
