Replaced Air Filter and now she idles badly and stalls

Thanks for the reply Kenny.

I read it came pre-oiled so I didn't do anything before I put it in. It didn't look heavily oiled so I didn't soak it in kitchen towel or anything.

I put the old filter back (it goes in much more easily) and the same problem is there though it is not so prominent. Thanks for the tip on the reset, I'll try this next.

I also noticed that the seal on the air filter tray looks a bit worn. Could this be causing a vacuum problem?
