After that wicked storm this weekend i decided to take the focus out for a spin. The car struggled to start so after it finally started i popped the hood and there was a mouse nest on spark plug 1. The S.O.B. had bittin off chunks of the firewall and made a nest. Now today i checked the intake air box and there was more stuff. How can i check that ducting that leads up to the air box. Why does it still stuggle to start sometimes. Any help is appreciated. Thanks guys.
