Recently, my spouse got into his car to go to work. Before he even made it down our long driveway, his car began making frightening sounds. Afraid to continue driving the vehicle to work, my husband decided to stay home for the day. After investigating the car, he traveled to an auto parts store in my vehicle. He purchased transmission fluid to put in his problematic automobile. Thankfully, the transmission fluid helped the car’s performance. Besides transmission fluid, you can find many other types of items to help you maintain your vehicle at an auto parts store. On this blog, I hope you will discover some of the most sought after items available at auto parts stores today. Enjoy!

The electronic fuel injection system on your car or truck can be challenging to diagnose and repair. The number of fuel injection system parts that could malfunction can vary from engine to engine, but many of them require computer diagnostics to pinpoint which part needs replacing.
Potential Fuel Injection Issues
A failing part in the fuel injection system on your car may exhibit as hard starting, rough idling, or loss of power when accelerating, and multiple sensors affect each one of those processes. The sensors in the electronic fuel injection system report conditions inside the engine and exhaust system to the engine ECU (electronic control unit). The computer will then adjust timing, fuel flow, and air intake to the engine and optimize the performance and efficiency.
If even one sensor is not working correctly, the result could be a false reading that causes the ECU to make adjustments that cause the engine to run poorly or stop running entirely.
One of the most common electron fuel injection system sensors to fail is the oxygen sensor in the exhaust system just downstream from the engine. There may be one oxygen sensor in the system or multiple sensors in different parts of the exhaust system, depending on the engine and manufacturer's design.
The oxygen sensors read the gasses coming out of the engine and can help the ECU determine if unburned fuel or excessive carbon monoxide is coming out of the tailpipe. When the oxygen season fails, a warning light will come on, and you may notice the car running rough or starting hard in the morning.
Scanning the computer will help pinpoint the problem, and an auto repair shop can often scan deep enough to tell which oxygen sensor is not working if you have several on your vehicle.
Air And Fuel Sensors
On the intake side of the electronic fuel injection system, the ECU depends on information from several sensors to determine what it needs to do with the fuel/air mix going into the engine. The TPS or throttle position sensor reports the position the throttle is in when you depress the accelerator to the ECU. Combining that information with readings from the airflow sensor, the manifold absolute pressure sensor and the manifold temperature sensor help determine how much fuel the engine needs to create a proper air/fuel mix.
When all of these sensors are working correctly, the system is efficient, but if one of them is malfunctioning, it can be challenging to determine where the problem is. Often, the best solution is to take the car or truck to an auto repair shop so they can scan the system, test the sensors, and replace the appropriate electronic fuel injection parts to correct the issue on your car.Share
