Honda Ignition Service Tips
Most Honda original equipment spark plugs have a life of more than 100,000 miles thanks to electrodes that contain precious metals like platinum and iridium. If the plugs fail sooner than the recommended interval, first solve any related problems before installing new plugs.
Modern Fuel Control Diagnostics: Sorting Through The Data Stream Maze
Adapted from Gary Gom’s article in ImportCar. When confronted with a fuel control problem on a modern vehicle, I’ll normally use short- and long-term fuel trims to determine if the problem is caused by one of many failures, such as a vacuum leak or a leaking fuel pressure regulator. If you’re like me, you’ll
Direct Injection And Carbon Deposits
In 1985, Saab began using the new Bosch LH fuel injection system, and Volvo and other carmakers followed suit. The system worked such that incoming air passed through an airflow meter that sent a signal to the engine ECU telling it how much air was going into the engine. The coolant temp sensor then told the ECU how cold or warm the engine was, and it opened and closed the injectors when needed.
