Great tip! I’ve been watching DIY videos, but they skip over those details. Any common mistakes I should watch out for?
One common mistake is not properly sealing the new valve. Make sure to use new gaskets to prevent any air leaks. Also, double-check that all connections are tight before starting the engine.
Thanks, William! I would have probably reused the old gaskets. Do I need any special tools for the gasket replacement?

No special tools are needed, just some patience! You can use a scraper to clean off the old gasket material, and a little gasket maker can help seal things up if needed. Just be sure not to overdo it!
LOL, got it! Any recommendations for specific gasket brands or types? I want to do this right the first time.
I’ve always used Fel-Pro gaskets, never had an issue with them. Just make sure you get the one specifically for your Silverado model year!
Heard good things about Fel-Pro. I might also check my manual for specifications, right? That’ll help me get the correct parts.
Definitely check your manual! Also, don’t forget to reset the engine’s ECM after installation to clear any trouble codes. It can save you from confusion later on.
Thanks! That sounds crucial. I do have a code reader; just want to make sure I handle everything correctly.
If you don’t have a code reader, you can also disconnect the battery for about 15 minutes to reset the ECM. Just make sure you have any radio presets backed up!
Perfect, I appreciate all the help here! This seems easy enough if I take my time. Any last-minute advice before I tackle this?

I’ve had similar issues with my Silverado. First thing I’d suggest is checking for any error codes using an OBD-II scanner. Common codes related to the idle control valve include P0505 and P0506.
That’s great advice! I had a P0505 code once, and it turned out to be a loose wire on the idle control valve. Be sure to check all connections too!

Definitely check those connections! Also, perform a manual test on the valve. Apply voltage and see if it opens and closes smoothly. If it’s sticky, it may need cleaning or replacing.
So true, xrobinson. I had to take mine out last summer to clean it, and it really helped with the idling problem! Sometimes it’s just about a little maintenance.
Thanks for that tip! I’m curious, how often should one ideally clean the idle control valve?
In general, it’s good to check it every 30,000 miles, but if you notice irregular idling or RPM spikes, do it sooner! Consistent maintenance can save headaches later.
Good to know! Besides cleaning, are there other potential issues with the idle control valve that could be related to it not functioning properly?
Yes, the throttle position sensor (TPS) can also affect the idle. If the TPS isn’t calibrated correctly, it might send incorrect signals causing idle problems.
