My car has a vacuum leak that requires removing the intake manifold to fix. It is our only car, so we've been driving it like this for a few weeks so Chris could fix it over summer break. He even drove it earlier today to the parts store.
When he took off the manifold, this is what he found:
I don't know. I don't know if I want to know. I'm just amazed that a) the wiring is intact, and b) it hasn't caught on fire.
