Are those aftermarket headlamps and running/signal lamps? If so, are they parts you sell?

I replaced this idle air control module on my 98 ck with 5.7 and it fixed my idle issues. My truck idled just fine until warmed up and then idled at about 1400rpm and that was a real pain of course. I used this video to show me how and it took me less than 1hr.

A couple tips on these. First, you must make sure the pintle on the new valve is not out too far. For my truck (99 k2500 7.4l) the spec says 28 mm from the tip of the pintle to the flat mounting surface. If the new one is out too far you can gently push it in. A drop of oil on the the o-ring on install will make sure you don't pinch/cut it. The relearn procedure for the 98-99 trucks is key on for 5 seconds, do not start. Key off for 10 seconds. Done.

+John Innis Thanks for the feedback!

Just clean the piston in it with carb cleaner, put it back in, and it will usually work fine. - they're usually carboned up, dirty, is the problem. No need to buy a new replacement one.

I have a 99 chevy silverado that it idles at low rpm also the battery voltage drops to 10 and as soon as i gas it the battery voltage goes to 14. Any suggestions i thought about changing the IACV

[@M3GAN3116]

Do you need a torque the new idle control valve ?

[@CentralCanada]

Just tighten securely !

[@Gkitchens1]

Is there a relearn procedure?

[@americanwhiteboy715]

Is this part able to be reset

[@jonbianchi2676]

It would be nice to show the re learn process

[@EataPeachMike]

there's a relearn process and do u know it?

[@CentralCanada]

Re-learn process ? My copy of "Haynes 24065" pg. 6-20, states; Install the IAC valve and tighten the screw(s), .....ooops can't share according to "All rights reserved/copyright" So can't potentially bring grief to 1A Auto !!

[@jeffduncan2519]

How do you know when that is bad on your car what are other signs

[@williamclarkson7099]

Really high idle

[@zx001961]

I have a problem with a 99 Silverado runs good when it's cold once it warms up it runs like crap have no code 02 sensors are new A-1 Auto from you It's driving me nuts Fuel pressure is between 45 and 48 it might hit 50 like to know why it is missing so bad when it warms up can you help

[@Franklinveterinarycenter1of4]

Cam sensor

[@travistaylor2469]

What if when you start it it serges idle up and down then shuts off, but only stays running when applying throttle

[@Lucky13tiki]

Arent you suppose to do the reset procedure

[@deeaguilar7645]

My 97 gmc sierra wont go over 30 mph any suggestions?

[@805BeachRecoveries]

Do rpms keep climbing but it won't go faster than 30? If so, it might not be shifting into the higher gears... might want to look into the solenoids in the transmission if that's the case

[@dannelyssilva1571]

How yo calibrar the pin?

[@leswalker2639]

I was wondering where that air flow sensor was answered my question thanks

[@heartbeatstorm983]

Question.. Where is the idle control valve on a 1985 gmc sierra 1500 truck and does it even have one.???

[@chevy8588]

Shouldn't you disconnect battery?

[@CentralCanada]

Not according to Haynes #24065, pg 6-20 ; presumably disconnecting the electrical plug does the trick' !?

[@KTHKUHNKK]

Hi guys I recently bought a bunch of front end parts from you guys and I'm very happy. I have a question now please. I just replace my IAC

[@KTHKUHNKK]

I replaced my IAC on my 4.8 2000 GMC Sierra. But now it idles at 2000 RPM can you help me out with this problem. Thanks Keith Kuhn

[@1AAuto]

+KEITH KUHN Hello, we aren't really able to diagnose vehicles like that. If you aren't sure what's wrong with it you can take it to a local mechanic for a proper diagnosis. Thank you! 1AAuto.com

[@EataPeachMike]

@@KTHKUHNKK did u fix that issue and what was it? I have a 97 GMC that's doing the same thing

[@davemcmurrick7962]

Wow, looked like a rats nest in the back of the filter box.

[@WildSuns42]

So true, and that really should have been cleaned out

[@9056aaron]

It would be nice if you showed that you put a new valve not the same one

[@lesglover6515]

Why does it matter? They showed you how to replace it I guess I don't understand why you need them to put a new one in?

[@eliasvite7324]

Chido chido

[@onemichaelmarsee]

All those extra steps for nothing.
