The following pdf document provides step-by-step documentation on replacing the rear shocks on a 2007 Honda Accord.

P1157, P0134 and LAF (Wideband O2) Sensor Replacement
The following PDF shows the procedure for replacing the upstream wideband O2 sensor (technically, the LAF, or Lean Air Fuel sensor).
Ignition Coil Waveforms
The ignition coil current waveforms can be monitored using a relatively inexpensive scope and current clamp. This technique can be used to diagnose problems with individual coils as well as some spark plug problems. The following PDF shows known-good ignition coil current waveforms as well as what they look like under a few fault conditions (ignition coil open and ignition coil short).
Inside a Lower Ball Joint
Here’s a quick look inside a Honda OEM lower ball joint. Interestingly the ball socket has upper and lower plastic wear surfaces:
Fuel Pump – Current Waveform
The health of the fuel pump and its operating speed (RPMs) can be rapidly assessed by a quick look of its current waveform. The shape of the current waveform, pump speed and average current draw are good parameters by which to diagnose a failing fuel pump. Details of the procedure and known good fuel pump waveforms are contained in the following PDF file:
Relative Compression Test
The relative compression test monitors starter current (via a current probe and scope) during cranking to get a quick gauge of the compression of each cylinder relative to the other cylinders. This is a quick and easy test which can be used to check for any significant loss of compression in a cylinder. More details, including known good waveforms are in the following PDF file:
Starter Rebuild
