First off my car idles a lil funny, its at 800rpm and jump to almost 1000rpm , it would do this back and forth and if i let go of the brake it would rev a lil higher.
Also when i drive and step on the gas (attemping to floor it kinda) it lags like the mph would jump or the rpm would.Also when i start my car up in the morning(cold start)
I would need to keep my foot on the gas to keep it running and if i didnt it would die right away, its been doing this for almost 2 years. When shes warmed up later in the day i wouldnt need to do it anymore.

I took it into the shop and the said my Idle Air control valve needed to be replace

1.8 HR to replace (135$ in labor)

And the Part (IAC) was $306.01
And shop supply (3.99$)

total of $445.28

I wanted to see if anyone knew how to replace this so i can save some money thanks

its attached to the bottom of the throttle body.
there is a how to somewhere on blocking off the coolant lines running to it, that will give you an idea of hwats involved.

a quick run down would go like this:

remove throttle cable,

loosen 4x14mm bolts holding on the throttle body noting that the longer bolts go in the bottom holes

unplug TPS and AIC

remove the larger middle hose connected to the AIC valve

clamp off the 2 water lines, then dissconnect them from the AIC valve

use a impact screwdriver to loosen the 4 screws holding the AIC in place without stripping them.

take it off, and replace it iwth the new one.


installation is the reverse of removal.

its not a hard thing to do. just have your car be cool so when you take the coolant lines off you dont get a shower. you may also find the part cheaper online. i thought i needed one so i looked all over the place online and found some good deals.
