• To help you have a better idea of what is going on today with A/C technology (and problems) let's quickly review the past, focus on the present and peak at the future regarding how vehicles are supposed to save fuel and still keep us cool.

  • Ford also had a similar procedure sheet for these engines when they had performance concerns, and the technicians had to fill them in for warranty as well. These sheets worked well to find concerns in a timely manner.
  • Toyota is convinced that hydrogen fuel cell technology is the future of transportation.  Could this really be a sustainable model for the future?

  • Since the introduction of fuel injection on the internal combustion engine (ICE) more than 100 years ago, there have been many changes to this system.
  • Whenever I’m pondering the possible cause of something like a hesitation/stumble concern, I find it particularly useful to draw on the experiences I received tackling drivability issues before fuel injection was the order of things.
  • European vehicles with drivability problems can and do get turned away from the service bays by many of the best technicians around because they’re just not comfortable working on them. But it doesn’t need to be that way.

  • A professional repair is one that is done completely. Doing a repair completely means completely solving the problem, completely resolving the customer’s concern and completely preventing it from ever happening again, if possible. 
  • Ford’s Pinpoint Test Z can teach you how vehicles work by grouping inputs and outputs that are related to each other and most likely will show a concern caused by certain problems. And it will help you learn the test procedures that Ford uses throughout their service manuals.
  • The impossible is upon us — the ability to see into the internal combustion engine while it is running. 
  • Today’s average citizen seldom considers the Jeep an offspring of a hero, although there are still those tried-and-true followers who connect the present to the Jeep’s star-spangled past. Transformation into the vehicle we all know and love today was not without difficulty, and the latest version of the vehicle is posh compared with its WW II grandfather. 
  • In the past, it was my practice to peek in on several classes to gain an overview of what was being taught, but this year I wanted to be a student as much as a reporter and decided to choose among the variety of classes offered and sit through the entire session. 
  • While there still might be some types of racing that keep it simple, the use of data acquisition devices has become relatively affordable for most forms of racing.

  • From time to time I get phone calls asking for information. I really love the calls that start something like this.
  • Entering the realm of hybrid repair can be a daunting venture for many technicians and shop owners. Servicing Honda Integrated Motor Assist (IMA) vehicles is a great way to get your feet wet.

  • In theory, diagnosing a misfire should be simple and straightforward – just figure out which cylinder isn’t operating properly and then figure out why.
  • We all had to start somewhere. No one was born a drivability expert, though some are gifted with a natural talent for reasoning through even the most difficult of diagnostic challenges.

  • This past decade has seen automotive technology changing at an exponential rate. One change that often misses the attention of most of us involved in drivability diagnostics is the fuel itself.

  • Is the cause of a P0171 the same thing on a Ford 5.4 engine as it is on a GM 4.2 engine?
  • The Jeep was first introduced for military use, but has undergone continuous reinvention to become a loved civilian vehicle.
  • Diagnostic experts weigh in to discuss the opportunities and pitfalls of dealer level module replacement and related functions.
