I'm having an issue whereby the engine at idle is revving up to almost 3k rpm making it almost impossible to drive safely.

I'm trying to hunt down the issue and initially this is pricking my attention..

This is continually ticking or clicking...what is it?

I'll do the vacuum leak check also before heading into the icv clean but just wanted to be sure I wasn't missing something sitting under my nose.

Turns out it's a fuel tank breather valve....still not sure if it should be ticking though.
