ETC and engine light are on and vehicle doesn't want to turn on... What do I do?

From google search: "This problem can sometimes occur due to dirt entering the throttle assembly. It can bring codes on relating to forced engine shutdown, which sounds dramatic at best. Normally a good cleaning of the throttle valve assembly cures this fault. It happens because the system fails to see throttle response or closure within parameters. This should be your first action to take, rather than spending money needlessly... Hope this helped?"
