Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or mass air flow (MAF) sensor to address a P0171/P0174 “lean-condition” DTC with no result. In all likelihood, the technician didn’t consider the possibility that the vehicle’s fuel might be contaminated with E85 gasoline, diesel fuel, stale gasoline, or, to a lesser degree, sugar and water.
Infiniti Creates Its Most Advanced V6 Engine Yet
The new compact and lightweight 3.0-liter V6 twin-turbo engine is the most advanced V6 gasoline engine that Infiniti has ever offered, striking an ideal balance between drivability, efficiency and performance.
Tips For Serpentine Belt System Inspection & Service
Like a tire, the friction between the belt and pulleys wears away at the belt, usually on the tops and walls of the ribs. Eventually the grooves of the pulleys will bottom out on the grooves of the belt, and then the belt will start to slip.
The Best Tests For Fuel Delivery Systems
In this article, I’ll explain how the Âbasics of testing fuel delivery problems has changed and how some of the most common mistakes in diagnosing fuel Âdelivery systems can be avoided.
Fueling Choices: Factors For Carburetion Or A Bolt-On TBI Fuel Injection System
If you’re building a performance engine, should you fuel it with a carburetor or some type of electronic fuel injection (EFI) system? If the application is a late-model vehicle that came factory-equipped with EFI, that decision has already been made for you.
The Connected Vehicle: Exploring The Next Frontier In Vehicle Communication
Connected vehicles have been with us since 1996 when GM introduced OnStar. This first-generation connected vehicle system pioneered the way for similar systems that were to follow. OnStar offered hands-free cell phone calling, GPS navigation, the ability to monitor vehicle systems for potential problems and to summon help in the event of a breakdown or accident. Since those early days, most import and domestic automakers have jumped onto the connected vehicle bandwagon and now offer some type of onboard cell phone, navigation and infotainment connectivity package.
Don’t ‘Blow By’ PCV Inspections
Anyone who services vehicles knows that the positive crankcase Âventilation (PCV) valve prevents crankcase blowby vapors from escaping into the atmosphere by siphoning the vapors back into the intake manifold so they can be reburned in the engine.
Engine Coolant Temperature Diagnostics
While old-school cooling system service often Âfocused on coolant leaks and overheating engines, let’s begin thinking “new-school” by looking at modern cooling systems through the eyes of the engine coolant temperature (ECT) sensor.
