I have just noticed that my emissions control light has come on.
This is whats happening.
with the engine running it sounds like there is a throbbing noise coming from the exhaust.
also from the engine there is a ticking noise that sounds like chattering relays (quite loud).
i took the plastic engine cover off and some thing is moving while the "chattering is happening), not sure what it is , can post a pic of what is moving if needed.
After turning the engine off I could still hear the ticking noise for a few seconds.
Any help would be much appreciated.
