Although the IAC is supposed to last the vehicle's lifetime, various reasons may cause it to fail/malfunction prematurely. The most common failure mode is partial/complete jamming of the actuator (due to dirt/dust or even oil) where it cannot be smoothly controlled. The result is an engine that fails to maintain idle RPM and frequently stalls.
Idle speed, sometimes simply called "idle", is the rotational speed an engine runs at when the engine is idling, that is when the engine is uncoupled from the drivetrain and the throttle pedal is not depressed. In combustion engines, idle speed is generally measured in revolutions per minute (rpm) of the crankshaft.
A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
All idling is bad — and it's worse the longer you idle for — but idling in traffic or poorly ventilated spaces like parking garages or under overpasses "can be particularly harmful," Ganjian says.
The NHTSA said its Office of Defects Investigation (ODI) received 39 complaints and a number of “early warning” field reports alleging engine failure in GM vehicles equipped with the L87 ...
The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is ...
Car and Driver retroactively described the Fuego as being "shaped like a walrus with gas.” [91] Hemmings Motor News wrote of how "The Fuego soon developed a reputation for unreliable electronics and overheating issues, which led to head gasket failures if ignored for any length of time. The problem was likely compounded by a poor spare parts ...
Volkswagen is recalling more than 271,000 SUVs in the U.S. because the front passenger air bag may not inflate in a crash. VW says in documents posted Wednesday by U.S. safety regulators that ...
