Spent three hours on a 2007 Civic's EVAP code because of a hidden hose
Had a P0455 on a customer's Civic that just would NOT clear after the usual checks. I replaced the gas cap and smoke tested the system twice, finding nothing. Turns out a tiny vacuum hose behind the intake manifold had a hairline split you couldn't see without a mirror. That little thing ate up my entire morning. Anyone else have a simple code turn into a major hunt recently?

Ever notice how the smallest, hidden flaw can cause the biggest headaches? It's like that in so many things, not just cars.

Yeah, that "smallest hidden flaw" thing is so true, I had a coolant leak from a pinhole in a heater hose.

You know, I used to think the big obvious problems were the real time killers. But that line about the smallest hidden flaw is dead on. I spent a whole day on a weird misfire that turned out to be a single broken wire inside a harness sleeve. It looked perfect from the outside. Now I start with the idea that the tiniest, dumbest thing is probably the cause.
