comment Is shifting to neutral on a decline more fuel efficient than keeping the gear engaged?
OK you got me there. I agree my comment isn't relevant as an answer.

I don't think it's quite so clear-cut. Unless the hill is steep enough to maintain speed with the transmission engaged, you're going to have to give it fuel to maintain (or get back up to) the desired speed. There are plenty of situations where coasting can maintain speed but engine braking can't. I suspect you're still better off engine braking than coasting with the engine idling, but if you shut off the engine while coasting, coasting is the clear winner.

comment Why don't car manufacturers treat rust-prone parts of a car with rust converter?
Rust converter is a treatment that reacts chemically with rust. It's not a preventive measure except insomuch as, by eliminating existing rust, you prevent it from spreading. Other preventive coatings are already used where appropriate.

comment Front left controller arm corroded and broke on my 2002 Hyundai Elantra
In terms of danger, you've probably understated it. Without the control arms in the proper place, the axle CV joints can come apart; at even moderate speeds their components are potentially dangerous projectiles. I had a separated CV joint blow a hole in an oil pan when it popped out of place. As long as there's not more damage the LCA should not be an expensive repair (I'd guess $70 in parts and 1-2 hours in labor) but please get a tow to the shop.

comment Extremely high then fluctuating idle at very cold temperatures
Thanks. My car's intake system does not appear to be that advanced (separate valves/regulators), but it seems plausible the ECU could be controlling the IAC valve to get this behavior intentionally.
