However, if you observe a sharp drop in fuel economy over a short period, such as a few weeks, this is a strong indicator of potential issues with the ECM or its associated sensors. The ECM relies on accurate data from various sensors to adjust the air-fuel mixture and engine timing....
Located on the throttle body of fuel-injected engines, the idle air control valve or IAC valve works with the vehicle’s ECU to regulate the amount of air coming into the engine while stationary to ensure smooth idling. Imagine the throttle plate as a door to your engine. The IACV is a...
Long-term fuel trim (LTFT)There is also along-term fuel trim (LTFT), which is a long-term compensation of the base air/fuel ratio. For example, if over time, the engine gradually develops a small vacuum leak, it makes the engine run leaner (more air and less fuel). In a long te...
After that, your doctor will send you for a pulmonary function test to assess lung health. You’ll do a spirometry test, which involves blowing air through a mouthpiece and into a machine that determines the amount of air you can exhale and the rate you can expel it. (The machine is al...
The coolant flows through the engine where it absorbs the heat and into the top of the radiator. The radiator is built of many flat aluminum tubes surrounded by fins. The air passing through the radiator cools down the coolant as it flows down the radiator. ...
In public and commercial buildings, the advent of stricter energy efficiency measures has often resulted in a tighter building envelope and possibly lower air exchange rate; this elevates the concentration of reactive (unsaturated) VOCs like terpenes (common fragrances) in the gas-phase and may incr...
The EVAP system is a sealed gas vapor system that pulls the fuel vapors from the gas tank and burns them through the engine instead of releasing them into the air. If there is a leak in the lines between the gas tank and the engine, or if the lines are blocked, it could trigger ...
Finally, close the hood and replace the reservoir top. The inside of the cap contains a rubber gasket, so turn the cap clockwise until it locks into place, making sure it sits securely over the reservoir hole as otherwise it could leak fluid or let air into the reservoir. ...

^ "The current blast of polar air is a symptom of global warming smothering our planet. With the tons of carbon we pump into the atmosphere by burning fossil, we have disturbed the air currents." Please explain further . . . I find the debate surrounding global warming involves idiots with...
