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.
Engine stalls
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.
After noticing that something is wrong with your car's engine, you decided to pull over on the side of the street. You spend nearly an hour wrestling with the engine as you try to diagnose the problem. It's just that, the problem wasn't really your car's engine but the air intake hose. And then you scream in frustration. Avoid this situation by removing the air intake hose from the list of suspects that cause engine problems. There are lot of things you can do to maintain the hose in its best condition, some of which are listed below.
Use more than just a rag
Any average car owner would rely on his trusty rag to clean an air intake hose, while some wouldn't even wipe it with a rag and just tap the dirt out. Clearly, this is not the best way to prolong the service life of the intake hose. There are cleaners sold in the market which you can buy; you can even ask your trusted service center to do the job for you.
Flush it every 30,000 miles or so
The air intake hose is a good spot for dirt, dust, or oil to be accumulated. This is something you cannot avoid regardless where and how carefully you ride. To avoid having a buildup of dirt in the assembly which can cause the engine to stall, we recommend that you flush the air intake hose assembly roughly every 30,000 miles or so.
Keep in mind, however, that the buildup is not completely determined by the number of miles your car has. Even if the vehicle is left at home most of the time, dust can still make its way into the hose. It would be best that you monitor the status of your engine; if idling starts to become tougher, it may be a sign of dirt starting to build-up inside the hose.
Do not do a patch job
Leaks are common problems for your Toyota Corolla air intake hose. Car owners would probably recommend that a patch job would be enough to keep the engine running, but we tell you that you may very well be making the problem worse. Sealers applied on the hole can fall out and help contribute in the build-up of dirt. We recommend that you take the hose out of commission and just buy a new one.
