comment Connecting to the Battery During Emissions Testing to Measure RPMs?
If you measure the voltage when the engine is running, you can see a ripple (it's not constant at 14V) and this ripple corresponds to the current draw from the battery to fire the spark plugs, ie one dip per plug firing.

that's one of the figures as well, I guess

comment Can you still “motor” a manual transmission car with the starter motor?
Also, the ability to jolt forwards was not really an intention - it causes damage and was only ever suggested for extreme emergencies. Some cars will even flag up an error condition requiring a visit to the garage on the first attempt at this (I'm thinking Citroens especially...)

no comprende - manuals are still by far the most common type in Europe. It may be different in the US, but remember we have a global community here.

comment Diesel engine vs petrol engine characteristics
Hi lexeter, no reason to delete duplicates generally. They act as a stub redirecting to the other one.

comment Diesel engine vs petrol engine characteristics
Actually, after posting my answer, I see this is basically a dupe in every way except the vibration, and the vibration is directly linked to the same cause so I'll vote to close as dupe.

comment which is more popular brake, disc brake or drum brakes in passenger cars in US? can anybody give a rough idea about percentage
I'm voting to close this question as off-topic because it's not really about maintenance. It's the sort of thing someone may study to get a historical vs modern view (as older cars had drum brakes and newer ones tend to have disc brakes) but it would require a lot of assumptions (eg is this cars registered as road legal, farm vehicles etc) - so I just think it's too broad for here.

comment How often do you need to run a car?
Catalytic converter - clever trickery in the exhaust to convert some of the emissions to more harmless gases. If it doesn't get hot enough this doesn't work well, and you end up with a cat containing water/acid so it corrodes fast.

comment How often do you need to run a car?
I babysat a friend's classic 500bhp Jaguar that he had let sit with less than one drive a month. It was much happier once a week, but damage already done.

Worth rechecking the fuses then Shanna

no lights or gauges? I'd suggest flat battery. The cause of that could be bad alternator, short, bad battery...

comment Tire Maintenance
Interestingly, of the 3 options, rotation is the one I never ever use. I always replace all 4 tires every time. Caveat: I always buy 4WD cars, and I get 10k miles out of them at most, so this may only be relevant to folks in a similar situation.

comment I have replaced my brake cylinders, but the brake pedal goes to the floor
chris - I had to edit to make the question readable. Can you please confirm I haven't changed the meaning.

comment Do I really need to wash the outside of my car?
Washing it when the roads are muddy/salty actually makes more sense. You can get that crud out of the places it has been forced since the previous wash, and a wax coat helps it stay out.

comment Do I really need to wash the outside of my car?
That said, I drive Subarus now, so I do a lot of off-road. So I wash them once a month, strip and repaint the wheels once a year, and never detail (to me that is a waste of effort, as I don't care about the looks of the cars - I just don't want them to rust)

comment Do I really need to wash the outside of my car?
Peter - this is categorically wrong. I grew up in the Orkney Islands: even worse for salt than the US Northwest! Washing cars was essential. Unwashed cars would rust through in 8-10 years, both through salt remaining on the car's surface and cracks, but also through salt and water being held against the surface by dirt/mud/etc. You wash to get all the salt off.

comment 1996 Toyota Camry unlocks and locks itself
Also worth checking battery - some locking systems could misbehave on voltage drops. They shouldn't, but I've seen it happen.

njzk2 - you almost always brake with the transmission in gear!

comment How to deal with a hot turbocharger
You see this all the time in areas where turbocharged cars are common. Here in Scotland I see it frequently.

comment Why do cars still use mechanical blinker relays?
As an off topic aside - while I agree mechanical parts are not as likely to be able to last as long, in reality, build standards were much higher in most consumer industries back in the day, so mechanical parts still seem to last longer than electronic equivalents in a lot of situations
