Common Problems with Your Toyota Corolla Air Intake Hose
You install a new air intake hose on your Toyota Corolla and assume that everything will go smoothly for years. But after some time, that assumption proved to be too ridiculous as you start to notice that something is wrong with your Toyota Corolla air intake hose. Here are some of the things you may have noticed:
Engine idles too fast
You notice that the engine idles too quickly every time you take your car out for a ride. The most common reason for this problem is the air intake hose; problems with the fuel injection and air bypass adjustment screw can also cause this but they are rarely experienced.
Being the primary suspect, your Toyota Corolla air intake hose should be checked for looseness or damage. In most cases, the hose became too loose which causes air to flow past the throttle. This then causes the fast idling of your engine. There are also chances that you have a worn out or a damaged hose. In either case, replacing the part is the only way to go.
You notice that your engine stalls and that there is a whistling sound coming from the assembly. The problems are likely caused by a leak somewhere in the air intake hose. Leaking can cause a weird fuel mixture and irregular combustion, which then cause the engine to stall. The whistling noise you can hear means that air enters the intake hose through a hole.
Most car owners would tell you that patching up the hole would be enough, but we are here to tell you that it is not. The only way to properly solve a leaking intake hose is to replace it.
Dirt buildup inside the hose
To take the problem of leaking further, there is also a chance for dirt or dust-or both-to build-up inside the hose. Because of the cracks or holes on the intake hose, dust can enter the assembly and be accumulated. This will eventually cause your car's engine to stall and may even enter the engine for a more serious damage. To solve this problem, you would need to flush the intake hose often to avoid a buildup of dirt.
