Yeah, @wesley139, that paperclip trick is a lifesaver for sure.

Man, that's the worst. Those generic P-codes are useless, you need the manufacturer specific stuff. I learned that the hard way on a Chevy with a weird misfire. My old Autel would just say "random misfire," but a buddy's better scanner pulled the exact cylinder and showed the injector waveform was dead. Saved me from swapping coils for nothing. Don't cheap out on the main tool, it costs you more in labor.

Paper airplanes are a legit test of aerodynamics though. That's basically applied engineering.

But is it really that deep? They probably just forgot to update the help page.

My old REI Half Dome had the same thing happen at Big Bend. I ended up sewing on a new #5 YKK coil zipper from a repair kit, which took about an hour. The key was using a heavy-duty needle and waxed thread. It's held up for three seasons now.
