Diagnosing An Intermittent, Poor-Run, Hard-Start Complaint That Stumped The Local Body Shop
This month we’re going to be looking at an intermittent poor-run, hard-start complaint on a 2012 Hyundai Sonata. This car came to us by way of a body shop with which we work closely.
Ride Control Systems: Matching The Components To The Application
During the fall of 1989, when I was working as a mechanic for an off-road desert racing team, we raced the famous Mint 400 held in Las Vegas. By mid-race, our truck came into its pit stops with the shock absorbers so overheated that the polyurethane bushings were literally melting out of the shock mounts. Worse still, as the shock absorbers began to fail, so would the leaves in the truck’s leaf-spring suspension. Despite the suspension problems we experienced during the race, we were lucky enough to win our class. But the lessons I learned about the importance of matching the shock absorber to its application endure to this very day.
Diagnostic Solutions: Ride Control System Protocol – Matching The Components To The Application
Import Specialist Contributor Gary Goms recalls his days of working as a technician for an off-road desert racing team and notes this lesson learned that holds true to this day: matching a shock absorber to its application.

Tech Feature: Mazda6 and Mazda3 Driveability Diagnostics and Electronic Throttle Control
Drive-by-wire throttle control systems are pretty much trouble-free but have to be taken into consideration as you perform routine service and diagnose problems, and it changes the way you service these cars when it comes to cleaning the throttle plates, advises Bob Dowie, import specialist contributor, who also covers electronic throttle control’s tie in with ABS and VSC systems.

Active Safety Technology: Adaptive Cruise Control, Lane Departure Warning & Collision Mitigation Braking
A vehicle that stops itself may sound like something out of a futuristic sci-fi movie, but the technology is here and now. From collision mitigation braking to adaptive cruise control, find out how many of today’s next generation active safety systems come into play.
Chassis Control Engineering & Application
It is a common mistake to look at a vehicle’s chassis and suspension system as just components that are either good, bad or broken. It should be looked at as a system. Understanding basic terminology and vehicle configurations is important to the technician for maintaining or returning that new car chassis control and performance. It
Getting a Grip on Traction Control
The basic principle of traction control is rather simple. A tire is breaking free and starting to spin so we’re going to place a drag on that wheel so that two things can happen. One is we want that tire to have a chance to regain its grip on the road surface. And two, we
Tech Tip: Evolving Ignition Control Systems
The key to diagnosing many cranking, no-start and stalling problems found on the late-model import is to understand how the crankshaft and camshaft position sensors function and what their mechanical relationship is to each other. During the past 30 years, ignition control systems have evolved from distributor-type, to distributorless, to coil-on-plug ignition systems. Similarly, fuel injection systems have ….
