Note for answers - the Accord 2000 is a front-wheel drive car with an open differential.

comment 2000 Honda Accord Shakes under acceleration
Where are you feeling the shaking? Is the whole vehicle vibrating? The wheel? The shifter? Do you notice the same thing if you accelerate in reverse (carefully!)? Is the behavior the same in every gear?

Do you see different behavior in different weather?

Please feel free to bring off-topic questions such as these to the chat. You'll likely get more useful information without the stricter Q&A requirements of the main site.

comment Exposed tire wire- safe to drive home?
@Paulster2, I don't think so: look at the wear patterns: the inner edge is worn flat. The middle and outer grooves are nearly untouched. I think you could hide a pencil in there, much less pass the penny test.

comment How does cold, dry weather affect horsepower?
(Okay this is to not-Ellesedil): humid air and water injection are not the same thing. Water injection is still water droplets (small ones admittedly). They don't turn to water vapor (i.e., humidity) until evaporation or a phase change (if the air is at or near 100C) occur. That evaporation / phase change absorbs plenty of heat and reduces the temperature enough (benefit) that the increased humidity is offset (cost). Personally, I would rather keep my intercooler cool - that'll cool the air without bumping humidity.

Page 179 of Maximum Boost by Corky Bell: "David Hobbs ... could feel a power loss when the sun came out from behind a cloud."

comment How to determine type of battery
I agree: this is largely a don't care for normal operations. The best reference might be the big book in the shop: look up your particular vehicle and they'll recommend a specific battery for you.

comment How does cold, dry weather affect horsepower?
You're almost certainly thinking of David Hobbs. Legend says that his butt dyno is so finely calibrated, he could detect the difference in horsepower resulting from driving through the shade.

comment Wheel change/balance leading to continuous braking
That might cause a change in braking but I would expect a secondary symptom of a crazy loud screech on braking.

comment My a/c goes in and out at random times. Help!
I think you're right: this sounds like the refrigerant has leaked down to a marginal level. The compressor is turning off right away because there's not enough for it to compress. Now, that said: if the refrigerant has leaked out, there's still a leak in the system that needs fixing. I was just reminded of that fact when I didn't replace the O-rings before recharging the system: chat.stackexchange.com/transcript/message/15399775#15399775

comment Golf mk3 TDI has pressure in the cooling system
@TomMacdonald, I might be completely off base. Hopefully, you'll find out the correct answer and tell us here.

comment Golf mk3 TDI has pressure in the cooling system
Just to clarify: when you say "pressure cap", you're talking about the cap on the radiator itself, right? We aren't discussing the expansion / overflow tank? That's the separate plastic container where the level raises and lowers based on the current temperature of the coolant.

comment Golf mk3 TDI has pressure in the cooling system
I find points one and two to be the most interesting. Does your car exchange heat between the oil and the coolant? E.g., on mine, the oil and coolant pass in close proximity in a heat exchanger. I'm wondering if you're seeing much higher coolant temperatures (and therefore pressures) than normal due to prolonged periods under boost.

@Paulster2, now turn it into an answer....

comment What could make a noise when I decelerate with a manual gearbox?
Your gear level question is interesting: have you tried damping the vibrations of the gear lever while the noise is occuring? If it's the gear lever, even the lightest torque will change the sound.

comment Gurgling sound from blow off valve at medium RPM
@Nick, exactly - in my case, the stock valve vents back into the intake. It's likely that I have a similar sound going on at some particular midrange RPM but I can't really hear it due to the muffling of the intake manifold.

comment Gurgling sound from blow off valve at medium RPM
As always, it's your car so you have to decide what to worry about. That said, I don't think you need to worry. Compressor surge could cause damage (given enough time). A burbling blow-off valve is likely just a quirk.

comment Audio player doesn't read some songs
This question appears to be off-topic because it is about an MP3-playing CD player. It's not clear that this has anything to do with this site.
