Ignition Misfires
A flashing Check Engine light and a P0301 to P0312 diagnostic trouble code is a sure-fire indication that one or more cylinders are misfiring. Occasional misfires may pass unnoticed, but a steady misfire is hard to miss. The engine usually feels rough, lacks power and uses more gas than usual. Sometimes a misfire may feel

Scan Tools: Tune In, Tune Up, Cash In
What is with all the new interest in music? Everywhere in the car industry and the aftermarket, people are talking about the “tuner” market. Are they talking about the old stereo of Dad’s in the den? Maybe they are talking about the newest disk player that can support mpeg and iPod? No! The interest is
Tech Tip: Engine Analyzers Combine the Capabilities of Many Diagnostic Tools into One
When most people think of an engine analyzer, they think of a big box console with automated test capabilities that can detect a wide variety of faults. There are still some machines like these today, but many of the features of a traditional engine analyzer are now available in top-of-the-line scan tools.
Servicing Ford 4-Cylinders: Contour, Escort, EXP, Focus, Probe, Ranger & Tempo

All of these engines are overhead cam engines, some with a single cam others with dual cams, and all have timing belts that need to be replaced at
Servicing Import ABS Systems
Import anti-lock brake systems (ABS) are pretty much the same as domestic ABS systems. In fact, the same OEM suppliers who make the ABS system components for import vehicle manufacturers also make them for domestic vehicle manufacturers. The differences that do exist are typically limited to calibration, diagnostic codes and procedures, and wiring. The ABS
Transmission Service: It’s a Dirty Job, But Here’s What You Need to do It
Automatic transmission work has always been considered hard, dirty work. And rightly so. Pulling a transmission, especially on a front-wheel-drive car or minivan, can be a long day’s work. It usually involves supporting the engine while the transmission and subframe are dropped from the vehicle. Consequently, you need some type of engine hoist or engine
Investigating Intermittent Stalling Problems
Diagnosing an intermittent stalling problem can be a challenge, especially if the engine only stalls occasionally and won’t stall for you (only your customer). And if there are no pending codes, hard codes or history codes in the vehicle’s computer to give you some direction, you may find yourself guessing at a diagnosis. Every engine

Diagnostic Dilemmas: Navigating OBD II Scan Tool Diagnostics
Although some hybrid OBD I/OBD II versions existed as early as 1994, the current version of OBD II was introduced in 1996. Because OBD II is a scan tool-based diagnostic system, diagnostic techs have become much more reliant upon the scan tool as a primary method of diagnosing malfunction indicator light (MIL) issues. In addition
