Direct Injection Engine Problems
Gasoline Direct Injection engines go by many names including GDI, DI, FSI and more. Car manufacturers have introduced this engine technology in response to federal emissions and fuel mileage requirements. While these engines offer a lot of upsides as far as fuel economy, horsepower, lower displacement and fewer tailpipe emissions, they also have some downsides.
Wideband Oxygen Sensors Vs. Narrowband: Understanding The Differences
Wideband air/fuel oxygen sensors may appear similar to conventional narrowband oxygen sensors, but there are quite a few differences that you need to be aware of to service vehicles with this new style sensor.
Servicing R1234yf: Are You Ready?
R1234yf, tabbed the replacement for R134a, has been in service now for a few years on certain models from FCA and GM as well as several European models. R1234yf is estimated to be fitted on 35 million vehicles worldwide. The EU has already banned R134a as of Jan. 2017, and the U.S. will follow suit by 2020. While most independent shops haven’t had to deal with it yet, you will start seeing them soon, so you should be prepared to service them by getting the right tools.

Preventing Turbocharger Breakdown
With more and more vehicles employing a turbocharger to achieve power and fuel efficiency from a downsized engine, the importance of maintenance is more critical than ever. Up to 50 percent of turbocharger failures are due to oiling problems, which can result from the lack of lubrication or not cooling down enough after the engine is shut down.
A/C Compressor Replacement: Doing A Visual Inspection & Checking For Leaks And Debris Eases Diagnostics

Engine builders who used to see RYE at local races as competitors, will now be able to work directly with them and their vast resources when building their own engines.
Tuning In To The EFI Market
There are many variables that need to be calculated and calibrated when it comes to electronic fuel injection (EFI), but simple fuel flow is just the beginning. EFI goes far beyond a replacement for a carburetor, and the electronic part of the equation is where these systems seem so complicated. Many EFI systems give you the ability to control a wide range of parameters of the vehicle, so it’s more involved than simply controlling fuel flow.
