Junk yard IAC?

[koda6966]

Is this something that should always be bought new, or can I just pick up a junkyard one and call it done? Damn things are $200 new, and from what I've read cleaning them is only a temporary fix.

yes cleaning is a temporary fix, you can get away with a junkyard IAC, but obviously the best choice is a new one. assuming you have diagnosed it correctly

Damn things are $200 new,

is it made out of gold?

last i knew they were 45 bucks at autozone.

IAC's are Simple solenoids. They are Not worth remotely near 200 bucks. Pick a working one out of a junk yard.

Apply 12 volts to its leads.

If it clunks back and forth its working fine.

They are such simple things I always suspect theres another issue thats making the computer Run the IAC all the time or not at all. Or bad grounds or a short.

they may be simple, but they get dirty and get stuck very easy.. i agree 200 big ones is not worth it, but when it comes to long term performance a new one will beat a used one any day

Are you sure you can test them by applying 12v?.
I tried that last year and the wires welded themselves to the connectors just pryor to the wires glowing bright red and melting.
I tried a j/yard part on the motor and it did not control the idle either. After seeing what the part costs in the states I can't imagine what one costs here. As a tempory solution I removed the solenoid and made a plate with a screw in to allow the air bypass to be adjusted manually, warmed up the motor and adjusted the idle speed to around 750. When the motor is cold you have to keep the rpm up with the pedal for a minute or two but otherwise seemed to work fine. Ran like that for a couple of weeks until the cel came on, bummer. Thought to myself "perhaps I should plug something into the electrical connector" so I plugged the j/y part into the harness, tiewraped it to the intake and cleared the codes. It's been like that for almost a year now and still no cel so I'm not going to spend a fortune for a part that would cost me almost what I paid for the truck and might not solve the problem anyway.

This is for my Zx2, not my truck. Which is why it costs so damn much.

 

[koda6966]

Just checked auto zone, 100 dollars. WHOOT.

The places online that I usually buy parts had them all at 180-200.

 

[adsm08]

that is still a huge price.

 

[koda6966]

Better than 200.

 

[adsm08]

fair enough.

SOHC or DOHC? The SOHC version is $97.99 shipped at Amazon

 

[koda6966]

DOHC. I'm guessing that's why it's expensive. I found SOHC ones around 50-75.
