comment What is the small plastic dimple found on some front doors?
Exactly. It is also the thing that gets pried out of position when a bad person wants to steal things from your car. I was never able to get ours precisely back in shape on our old Honda.

comment Engine missfires when accellerating first gear
See Zaid's answer here (and cited above): he suggests MAF, fuel pump / filter and O2 sensors as possible culprits.

comment diesel pressure issue Fiat Punto 1.3 JTD
This sounds like the car is going into a "limp home" mode. Could you post the exact error messages that you are getting? I assume those are coming from some sort of OBD-II scanner or equivalent. FYI: my car can go into a limp home mode if the fuel filler cap isn't on tightly enough - that might be an easy thing to check.

comment 2002 VOLKSWAGEN GOLF CL 1.4 - No power for first 3 mins driving
Lorraine, it's great that your issue is fixed. In the interest of future visitors, it would be great if you could share a few more words about why / how you found out that the lambda sensor was bad and how you know if fixed the problem. At that point, you could accept your own answer and the next person to come in with the same problem would see this as a likely option.

comment What is the general rule, if one exists, for determining the difference between crank horsepower and wheel horsepower?
Don't forget that power and torque (in a car) are directly related.

comment Torque and engine power
I think this is really a duplicate - going to point it that direction.

comment What is the general rule, if one exists, for determining the difference between crank horsepower and wheel horsepower?
@Ellesedil, there is a difference. AWD loses more to drivetrain losses (which is what Paul is describing). You can think of it as if every mechanical bit between the engine and the wheels is adding to the frictional effect. So, for example, my AWD WRX is losing a greater percentage to drivetrain losses than a RWD BRZ. However, my WRX still ends up with a higher wheel horsepower number (plus the AWD is wonderful in the snow :-).

comment 2004 Hyundai Elantra stalling when tank is full
Here's a thing to try: if you can get the issue to occur in a place where it's safe to park and idle for a bit, hop out and open the filler flap (not the gas cap itself). There should be something like a white button near the gas cap. If you push that, you'll release some of the vacuum in the tank (if that's a problem). If that's part of the issue, you should notice an immediate change in the idle.

comment Which Honda cars are equipped with permanent AWD?
@Ellesedil, Subarus also have the additional plus of being totally awesome. There, I said it.

comment Oil leak should have changed oil not added
Could you add more information about the leak? How did you notice it? Any thoughts on where it's coming from? Are you sure that you aren't seeing air conditioner condensation (i.e., water)? I ask because it's super humid here and many cars have puddles under them.

comment Oil leak should have changed oil not added
The only possible "damage" I can see here is that Susan added some oil to old oil the she's about to change. So, she's spent a little money that she didn't have to.

comment 4 stroke valve timing diagram: if valves are open during TDC, wouldn't they hit the piston?
@midnightBlue, you are right: the engine has to be perfectly calibrated in an interference engine. Otherwise, there could be contact between piston and valve (which is, as you might imagine, bad).

Is there any reason not to buy a used generator and start from there?

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.
