i was changing my air filter today and what i think is a computer componet was in the way. It should be screwed in but wasnt for some reason so i moved it over. I start the car and runs fine. I had a small antifreeze leak which i fixed in a minn and go to start the car and i hear a loud clicking noise, the car idles sporaticly then dies. I have no clue whats wrong, please help!
