Do You Need Wheel Alignment? May be yes, may be not. It depends on the degree of Toe, Camber and Caster.
Second question is, if you do need alignment, what kind of package price should you choose? Because not all cars make the alignment adjustable, you may not want to pay the standard price without getting the benefit.
My car has over 150K miles & has never been aligned. The camber and caster are not adjustable by design. The toe is only marginal out of alignment, but in order to save my viewers money and time I decided to go through the professional alignment anyway. This video will show how the alignment is done in a shop with the state of the art laser machine.
If you have a Honda Accord & want to know the valid degree range, it is shown at the time 12:50 of this video.
This video shows 6 steps to remove the old oxygen sensor & 6 steps to install a new Oxygen sensor.
Starting from the beginning when you received an engine warning light, what do you do?
I got the P0141 code (you may have other codes). It indicates that too much time elapsed before the oxygen sensor began operating properly. Either the heating element on the sensor is not working, or the heating circuit is open, many possible places that the wires are disconnected. Since the engine light only comes on a few days after reset, I decided it is more likely the sensor is not working.
The 2nd question is should it be genuine OEM part or universal sensor? Of course you are interested in this: where is the cheapest place for the genuine Honda oxygen sensor?
Got the P0141 code which is: the controller tracks how long it takes for the oxygen sensor to begin operation. If too much time elapsed before the oxygen sensor began operating properly, it will set P0141. There are 2 possibilities:
1. the heating element on the sensor is not working.
2. the heating circuit is open, many possible places that the wires are disconnected.
I measured the resistance of the heating element, which is about 6 ohm. Since after reset the engine light does not come on until a few days later, I decide just to replace the oxygen sensor.
P0141 is for the “secondary oxygen sensor” when you order from Honda. Or the “downstream oxygen sensor” when you order from third party store.
I will order one from Honda instead of using the Bosch’s Universal Oxygen Sensor.

How to Change the Front Brake Pads on a Honda Accord
1 Park your Accord & engage its emergency brake (because emergency brake only applies to rear brake).
2 Remove wheel: loose nuts using lug wrench, lift the Accord’s front end off the ground using your jack and remove the nuts, and wheel.
3. Examine the Accord’s brakes, if you notice the rotor is deeply worn, scratched or gouged, you’ll need to have it resurfaced or install a new one. This video is about replacing the brake pads only.
4. Take a look at the back of the caliper. There are two bolts securing it against the rotor. Remove the bottom bolt, using a 12-mm socket wrench. Of course, turn the bolt counter-clockwise to remove it. You may now be able to simply lift the caliper upward, pivoting it on the top bolt. If not, try loosening the top bolt just a bit and try lifting it up again.
5. Examine how the old brake pads are positioned within the caliper bracket. Again, I find it easier just to take a photo of how everything looks so that you can correctly position the new pads. Once you’re clear on how it’s all put together, remove the old pads.
6. Use a C-clamp to compress the piston inside the caliper. Make sure you put an old pad between the surface of the piston and your clamp. The old pad will prevent damage to the piston. Sometimes pushing brake fluid back through the system may cause the master cylinder to overflow. You may simply use a rag to clean the drip.
7. Swing the caliper back down and bolt it into place. The “flexible” bolt housing may be in the way. Of course, if you removed only one bolt, tighten it snugly. If you removed both, remember to tighten both.
8. Bolt the wheel/tire back into place and lower the Accord to the ground. Once the Accord is on the ground, tighten the lugs.
9. Move to the other side and repeat the process to change the brake pads. You must always change both left and right brake pads. Never change just one side. When you’re finished with both left and right brakes, open the Accord’s hood and find the master cylinder. Clean any drips, look at the master cylinder. If you’ve lost any brake fluid, refill it.
How does an IAC work?
For an example of Honda Accord 2004, I will provide 5 options to fix the problem caused by the Idle Air Control unit (IAC). I will also provide the prices quoted for each option from various sources. This would help you to decide which option is the best for you.
