2014 Corolla CAI chirping noise


Asked by Jun 20, 2016 at 05:51 PM about the 2014 Toyota Corolla S Plus

Question type: General

I own a 2014 Corolla S Plus. I recently purchased a
K&N Cold Air Filter. I carefully read the instructions
and cautiously installed the CAI. I then test drive my
car with excitement until after a few minutes I heard
a chirping low noise when I am on gear and pressed
on gas, sometimes while changing gears. It's kinda
like a bird chirping noise. I checked and secured all
tubing and hoses to make sure it's tighten and they
are. I'm not sure where it's coming from. I also
thought it was a suspension problem because it
sounds like it is but it's not. I tried driving to rough
roads and nothing. May you please help diagnose
this case?

I'd like to add, I started noticing my gas gauge now faster consuming prior to the swap. I thought having CAI saves more on gas not depletes. Please assist. Thanks.


I know you won't like hearing this( I KNOW SOME GUY ON A FORUM GAINED 25HP) but a cold air intake kit is a complete waste of time and $. Also oil from the K&N filter Travels upstream contaminating the MAF which is one of the main signals to control fueling / fuel trim , did it come with a Dyno sheet showing the mileage and HP increase? Check out how much time you have invested in this CAI now? and $ and convert this to real study / learning, mean piston speed, thermodynamics, stoichiometric fueling, flow physic's and what really enhances engine performance. I do suggest this in the most positive way I want people to learn and think. Regards HERE READ THIS BASIC BUT ACCURATE, having a properly functioning Mass Air Flow Sensor is critical to the proper functioning of your fuel injection system and as a result fuel economy. If a MAF sensor is malfunctioning badly beyond a certain threshold it will cause the computer to display an error code that may alert you to a malfunctioning MAF. However, if the sensor’s elements are just dirty (oily) then it will be constantly misreading your air ratio and possibly causing lower gas mileage.


Thanks for your honest answer. I greatly appreciate it. I hope others can comment and assist me with my case. I am worried.Again thanks Auto_Centric. Hope all the best in you.
