Summit Racing Equipment Now Offers Mr. Gasket Cataclean Fuel System Cleaner
Cataclean can restore performance, extend engine life, and solve issues like hard starts and hesitation. Cataclean doesn’t affect fuel composition and is safe for use on gasoline, diesel and hybrid engines.
Troubleshooting Mass Air Flow (MAF) Sensors
Troubleshooting mass air flow (MAF) sensor problems can become a major headache for import technicians because the failure is usually one that involves a calibration error rather than an outright electrical or mechanical failure. Because calibration errors tend to be “gray-area” types of problems, we will begin by looking at the basics of how a “hot-wire” MAF sensor measures airflow through an engine running at various speeds and loads.
Servicing Chrysler’s Versatile 3.3L And 3.8L Engines
These engines have a mixed reputation for being high-mileage, dependable powerplants as well as noisy motors that can fail at relatively low mileage. Some 3.3/3.8L V6s have racked up well over 200,000-plus miles on the odometer with no major problems (except some oil burning), while others have called it quits at 70,000 to 80,000 miles.
Delphi Product & Service Solutions Announces 16 Oxygen Sensors Covering Almost Two Million Vehicles
Delphi Product & Service Solutions (DPSS) announces 16 new oxygen sensors covering more than 1.9 million Ford, Honda, Toyota, Mitsubishi, Cooper, GM, Nissan, BMW, Suzuki and Mazda vehicles from 2004 to present.

Diagnostic Solutions: Engine Coolant Temperature Sensors
Considering that roughly 1,500 or more different vehicle models are introduced into our domestic market each year, it’s becoming more difficult to predict how a Powertrain Control Module (PCM) will utilize data from a particular sensor or detect an out-of-range sensor in any single vehicle platform. The engine coolant temperature (ECT) sensor provides a good illustration of how many on-board diagnostic strategies have changed.
Catalytic Converters: Replacement Is Changing
If your shop is not in California, the replacement of the catalytic converter is simple and typically there is only one replacement option. Most shops understand that they must replace the converter and that using a test pipe or bypassing the converter is bad for business and against the EPA regulations and could result in big fines.
New York And Maine Delay Implementation Of New Catalytic Converter Standards
AAIA received a letter on May 21 from Jared Snyder, assistant commissioner for the Office of Air Resources, Climate Change & Energy in the New York Department of Environmental Conservation (DEC), announcing that the agency will delay enforcement of the June 1 implementation of six NYCCR Part 218-7.2 (c), adopted standards for new aftermarket catalytic converters.
Servicing The GM 3.1L V6 Engine
The General Motors 3.1L V6 engine enjoyed a long production run from 1988 through 2005. More than 10 million of these engines were built during this period. The engine itself went through continual evolution and improvement during its production life, including Gen II and Gen III versions, plus an “Enhanced 3100” version from 1999 to 2001.
DENSO Makes It Easier To Find The Right Oxygen And Air/Fuel Sensors
DENSO has just released their 2013 First Time Fit Oxygen and Air/Fuel Sensor Catalog that offers one of the most complete product lines in the industry, said the company. It includes 67 new oxygen sensor part numbers to cover an additional 7.7 million units in operation.
The Automotive Training Group Releases 2013 GM Engine Performance Course And Training Manual
The Automotive Training Group has released the 2013 GM Engine Performance 7-hour course and training manual. Like all ATG products, this new GM Engine Performance class covers all of the newest GM technology, but emphasizes evolving failure patterns on older systems as well.
Tech Tip: A Day In The Life Of A Contaminated O2 Sensor
Since the oxygen sensor is in the exhaust stream, it can become contaminated over time. Much like a spark plug, the oxygen sensor can be examined and “read” to determine what the cause of contamination might be.
