IAC & Throttle: 2 Simple Problems That You Can Fix On Your Own

There are a lot of compartments in your vehicle; many of them should be serviced by a professional, but that does not mean you can't fix certain issues yourself. The following are 2 things that could go wrong that you may be able to fix.

Dealing With Your Idle Air Control

One of the things that you can deal with on your own is the IAC valve. This little valve helps control the amount of air that enters your engine. The precision of air is crucial for proper combustion, which makes this valve quite important. The following are a few signs of a bad IAC valve:

  • One thing that you might see is erratic idle speeds that might cause a stall.
  • You might see some hesitation when you accelerate.
  • There is a chance that your car might stall when you turn on your AC.
  • Your car might stall when the load is too heavy.

To take care of this problem, just follow the steps below:

  1. Park the vehicle in a safe and leveled location.
  2. Be sure to let your car cool down if you were driving it recently.
  3. Wear protective gloves and glasses.
  4. Disconnect the red or negative cable for your own protection.
  5. Use your owner's manual to find the IAC valve, which looks like a small "t." The valve is usually at the end of the air duct extending from the air filter.
  6. Use your socket and wrench set to disconnect the two bolts holding the IAC valve in place. Disconnect the plug-like cable connected to the valve, too.
  7. Replace it with the new IAC valve, and secure it in place.
  8. Reconnect the battery when you are done, and that is it.

You can talk to your auto care specialist if you do not want to do the labor; he or she will also be able to confirm that the problem is indeed related to the IAC valve.

Dealing With A Dirty Throttle Body

Another simple thing that you might be able to deal with on your own is the throttle plates. These plates allow your car to read just how much power you are requesting. The symptoms are somewhat similar to a bad IAC valve with the exception of the following:

  • You might have trouble starting your vehicle. This means more cranking before your car finally stays on.

You can take care of this issue by simply cleaning your throttle body on your own. Follow the steps below to try to fix the problem that you are having:

  1. You want to make sure that you've parked the vehicle in a proper location. Let it cool down, and do not turn it on while you work on it.
  2. Wear protective gear, and disconnect the red or negative cable from the battery.
  3. Use your owner's manual to locate the throttle body. This is usually located directly at the end of air duct from the air filter compartment.
  4. You want to remove the air duct using your socket and wrench set or just a screwdriver (this does depend on your vehicle).
  5. The outer piece of the throttle body should be exposed. It is the performance part that was directly connected to your air duct.
  6. Use your socket and wrench set to remove the two bolts holding the outer piece in place. You will see the throttle body plate after this piece is removed.
  7. Use throttle body cleaner and wire brush to clean any gunk that you might see. Concentrate on the sides of the throttle body and on the plate itself. Try to clean both the front and the back of the plate.
  8. You can reconnect everything when you are done, and that is it.

Now you know how to take care of 2 simple issues on your own without spending too much money.

Keeping Your Car Pristine

A little fender-bender might not seem like that big of a deal, but frame damage can go a long way. When I got into a little accident last summer, I wrote it off and figured that it wasn't a big deal. Unfortunately, I waited until I had already burned through a few sets of tires to have my car looked at by a professional. The goal of my blog is to help other car owners understand the importance of having their car repaired right away, instead of procrastinating. You never know what kind of underlying damage your car has, but a professional can spot damage and repair it correctly.
