It is often asserted that series hybrids are not as efficient as parallel hybrids (citation needed) but this is only because they are being built with inefficient reciprocating internal combustion engines. The obvious solution is to use microturbines.

As a veteran owner of used vehicles, I am more than a little used to encountering automotive problems. When my Ford's charging system idiot light began to flash at low RPMs, I knew I had a serious problem coming my way. When it picked up to doing it on a regular basis, I realized that the problem had arrived, and unless I wanted to be buying a pair of deep-cycle batteries, I should find a solution, probably in the form of an alternator replacement. After doing a little research, I decided to install a later-model Ford alternator.

This is an abbreviation for "Model Year". Automobiles made in one year are frequently considered part of a different "Model Year". Some manufacturers use this term while others do not; Subaru is one that uses it in their own internal literature.

The Throttle Position Sensor (or "TPS") is an integral part of any electronically-controlled fuel system, even many carbureted systems. It is usually attached to one side of the butterfly valve which admits air into the intake manifold, while the throttle linkage is attached to the other. In carbureted systems, the throttle linkage may also have other functions; in fuel injected systems, it is the throttle position sensor which instructs the car as to how much fuel you are attempting to burn.

This is a Delphi Throttle Position Sensor that I purchased from autopartswarehouse.com. The cover arrived damaged. This device shows clearly the inner workings of the throttle position sensor. The part number on the sticker is 22633 KA040. The part number printed on the box is S10338-11B1. The UPC printed on the box is 89604 10589.

As I may have mentioned previously, my 1993 Subaru Impreza LS has a faulty throttle position sensor. I diagnosed it using a non-autoranging digital multimeter on the megohms setting. A better solution is to use an analog ohmmeter, or to follow the factory test procedure and connect a voltmeter to some of the pins on the ECU. So far so good. I ordered a cheap Delphi replacement part from autopartswarehouse.com, and the fun began.

As you may already know, I am the owner of a 1993 Subaru Impreza LS (GC5). While returning from a trip to San Francisco to attend the Power to the Peaceful festival (which was extremely underwhelming this year) in celebration of the three-year anniversary of my relationship with my lady Anna-Maria, a loud clicking noise was to be heard while accelerating and turning left. I easily identified this problem as a failure of the left front axle (I could tell by feeling the vibrations as much as by hearing the sound in this rather small car) and proceeded to research the issue of repair.
