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.
