How Do You Know if You Have a Bad Transmission?

A transmission plays an important role in the operation of your car. And if the transmission goes, it can be an expensive problem to fix. Luckily, many cars give off warning signs that it needs repair before it completely dies. Unfortunately, many people have no idea what these warning signs are. If you don't know what the warning signs are, don't feel alone. I was once in the same position and ultimately, it caused me to have to replace the transmission in my car because I missed these signs. I created this website to help others identify when it needs to be repaired. If you notice any signs of a problematic transmission, head to a repair shop quickly to save yourself a lot of money!

Car Wise: Idle Speed Issues Might Be Solved With This Simple Solution

Diane Bishop

The normal idle speed is usually 1000 RPM's, but this speed can be negatively affected. One simple reason you may be having idling problems could be connected to your idle air control valve. The following guide will show you how to replace this mechanism and help you detect the signs that your idle air control valve may be faulty. 

Signs Of A Bad Idle Air Control Valve

Your vehicle's computer uses the idle air control valve to control the amount of air that is allowed into your engine. A specific amount of air needs to mix with the fuel in your engine for proper combustion. This valve can fail, causing an improper air-to-fuel mixture that causes problems like your vehicle's erratic idle speeds. But the following are other signs that you should watch out for:

  • Your car's idle speed may drop, which can cause your car to stall. By this point the valve is defective, so it will block air, which makes the combustion process last longer than it should.
  • Getting your car to slow down to the correct idle speed may be difficult, which might feel like jerky deceleration.
  • You may notice backfire through your tailpipe. Your engine adds the fuel your car needs, but that fuel is not properly burned (with a faulty idle air control valve) since the air is not passing through your engine. 
  • There may be hesitation during acceleration.
  • Your car may stall when you turn your air conditioning system on. 

Talk to your auto care specialist about your idle air control valve to help confirm your suspicions. 

How to Replace Your I.A.C.V.

You will need the following to replace your idle air control valve:

  • Your socket wrench set
  • The owner's manual or repair guide
  • Safety goggles and gloves
  • A new idle air control valve that matches your vehicle
  • Your clean rag

Steps:

  1. Park your vehicle in a safe and leveled location. Allow it to sit there long enough so that you can work on it comfortably. 
  2. Put your gloves and glasses on. Disconnect the negative or red cable from your car battery. This is for your safety. 
  3. Locate the idle air control valve, which is usually on the left or right of your throttle body. The valve looks like a small cylinder with two small wings at the end of the cylinder. 
  4. Use your socket wrench set to remove the screws holding the idle air control valve in place. 
  5. Carefully disconnect the plug-like connector from your idle control valve.
  6. Remove the valve, and clean the area with your rag. Replace it with your new idle control valve, and secure it with the screws.
  7. Reconnect your plug-like connector to your idle control valve. And reconnect the negative or red cable to your vehicle's car battery. 

That is all you need to resolve this idle speed issue if it was related to your idle control valve. You can still talk to your auto care specialist to deal with this issue if you feel uncomfortable with any of the aforementioned steps.
