Your state DMV/RMV website should be able to provide this information.

comment 2001 Subaru Legacy L Wagon - Gas smell and light shaking
The hose that you've circled is connected to the intake manifold at the top, and to the injector line at the bottom, right? If so, it's the fuel pressure regulator vacuum hose. As far as I know, there shouldn't be any fuel in that hose, so I don't think it'll have anything to do with the fuel smell. However, if the regulator is damaged for some reason, I suppose there could be fuel in there; the regulator itself could also be directly responsible for the smell.

Seems to be related: Possible reasons for loss of power, engine shaking, and smell of liquid fuel (not burning, maybe duplicate.

comment Engine braking vs. braking in neutral on slippery & normal conditions
Please don't reply to comments and answers in your question. If someone brings up a point that needs refinement in your post, just integrate the necessary revisions with the rest of the text. All you did with the various @user segments was make this even harder to read and figure out what you're asking.

comment Found this in my wheel
At first glance, it looks like a rotor's dust shield, but the picture is pretty unclear. Can you light it a bit better? Also, what do you mean by "inside" the wheel?

comment Batery is above 12 volts but car ignition fades
Get the battery load tested. It may be the right voltage but not be putting out enough current.

Is it possible for you to just air it out for several hours with the doors wide open?

"Oily coating" to the tires? Do you mean wax? Oil destroys rubber.

Sounds like the pitch of the nuts you bought is wrong.

comment Toyota Celica battery light on but alternator appears okay on visual/auditory inspection
Where are you getting your figure of 13.8v as the maximum charging-state voltage? It depends on the car, but that's near the minimum of what any functioning alternator should read -- at least a volt above the battery's nominal 12.6. My car's alternator is specified by the manufacturer to run in the 14.1 - 14.8 range, depending on temperature. Going over 13.8v while charging does not necessarily indicate a problem.

comment Can faulty O2 sensor cause omission check engine light?
Other things besides emission problems will turn on the CEL; without knowing what the code actually was, it's impossible to say why it turned on or off. (Also, it wasn't your timing belt that was replaced, as Paulster noted on your other question.)

comment Vibrating sound and shaking when turning the wheel after changing timing belt?
There are two "accessory" belts on this car; if the arrows are pointing to the rear one in the picture, then the belt was for the A/C compressor, not the power steering pump, which is to the (car's) right of the alternator (just visible in the top left of this picture). The front belt drives the P/S and the alternator, and has no separate tensioner; the tension is adjusted via a bolt on the alternator. It's possible (even sensible) that both belts were replaced at the same time, but if tensioner was involved, that was the A/C belt's. @KingsInnerSoul

Also, if the cat failed within a year, something else is with your engine. I've heard people implicating failing head gaskets for that.

That's definitely the right ballpark. Catalytic converters are expensive. I'd think you could get a cheaper sensor, but I'm not positive.

The diagnostic code will indicate which it is. You should be able to get it read for free at your local parts store. There should be, as far as I know, three sections to your exhaust: first section includes the front cat and sensor, second section the rear pair, and the last goes back to the muffler. Unless somebody did something weird: my Forester had a piece of pipe welded across what should have been the joint for the two rear sections when I got it, so when I needed to do the rear cat, I had to do the end pipe as well.

Note that there's two cats and two sensors; you should double-check which are problematic.

comment Are there any double-DIN bluetooth stereo system that can connect to multiple devices at once?
The problem is that the result of "Are there any Xs that do Y?" and "Which X should I buy?" is the same: a speedily-obsolete list that's also a potential spam magnet. I don't think there's a good way to ask this on a Stack Exchange site.

comment Correct procedure and cost repair BMW timing chain (BMW 318ti)
My point in my comment -- which I don't seem to have expressed clearly -- was that there's no inherent reason for the previous owner to have replaced the chain at 86k. Thus, it's indicative of a possible problem, something the purchaser should be aware of and maybe investigate for related issues.
