comment 06 Chevy Cobalt ls 2.2 l . Replaced B1S1 O2 sensor still having issues
its possible that the newly installed oxygen sensor failed because it was defective.

comment '66 Doge Dart made a loud CRACK, engine almost stalled. The second time it happened, there was a puff of black smoke
any chance this was a backfire?

comment 2003 Honda Accord V6 - steering sounds
You "think" your power steering fluid level is adequate? What makes you think this? Have you checked it properly? Low power steering fluid level would be one of the most likely causes of this noise.

comment Controlling door locks via CAN bus
Quite possible that the headlights themselves aren't even on a CAN bus, instead relying on dedicated wiring and relays; while the headlight indicator is on the CAN bus with the rest of the instrument cluster.

comment VW Golf TDI makes a 'sneezing' sound on startup
@roryok I just watched your video. That's the same sound that I was describing. For what it's worth, ours has done this off-and-on for years now. It may grenade itself to pieces at some point, but so far so good.

comment Does the advantage of ballast make minimum weight rule pointless?
This question appears to be off-topic because it is about race regulations and race car design, not motor vehicle repair. Also, I would add that the minimum weight is not necessarily solely (or even primarily) directed at ensuring safety. It may be about leveling the playing field, as lighter is faster. There are minimum weights in sailboat racing, bicycle racing, etc.

comment How can you tell the difference between oil or transmission fluid in the antifreeze?
I wonder if leak detection dye (UV dye) added to the engine oil might be a way of isloating the leak to either engine or trans. Not sure the concentration of the dye would be high enough by the time it makes its way into the coolant system though.

comment 1999 jimmy with no heat in the cab
my first suspect would be a damper/diverter valve that is supposed to direct air through the heater core.

comment Daytime running light failure — one side only
OK, since it's dual filament, is the low-intensity DRL supposed to turn off completely when you engage the turn signal, or not? in other words, are you expecting the blink sequence to be hi-lo-hi-lo or hi-off-hi-off?

problem solved. turn on camera before starting car.

comment Does the advantage of ballast make minimum weight rule pointless?
@Tik I'm not sure I agree that "even in earlier days, you simply could not afford to have your star driver killed." Driver safety was not historically that big a concern to the vehicle engineers or the race track designers. This gradually changed I think it's fair to say that safety has steadily become more important in racing, especially F1.

Does this car use a single filament turn signal bulb or a dual filament turn signal bulb?

comment My car won't start. Is it that I ran it without coolant or is it my battery?
When you say you had zero coolant, you mean that there was no coolant visible in the coolant "bottle," or that you opened a coolant drain at the bottom of the system and nothing came out? If merely no coolant visible in the overflow bottle, then you were likely low on coolant, but not out of coolant. Either way, wouldn't prevent you from starting the car unless there had been some serious drama (major overheating) the last time the car ran. This would not have gone unnoticed.

comment Rear suspension much more sensitive to bumps than front
@vlsd depending on the bushing geometry, you may be able to put some load on the joint with a prybar or something and observe the way the bushing reacts. You may be able to tell which are most worn in this way.

comment Washing coolant system with dish soap to remove oil residue
Perhaps some context would be helpful here. Are you recovering from a blown head gasket or something similar where you know you had some quantity of oil in your cooling system, or are you considering this as routine/preventative maintenance?

comment Rear suspension much more sensitive to bumps than front
what type of vehicle? most likely this is not something "wrong" with the vehicle, merely a consequence of suspension design, weight distribution, and physics.

revised Is it okay to leave a car for 5 months without driving it?
removed somewhat misleading "non-operable" language. car is operable, just not operated.
