The engine on my '04 Chevy Silverado 1500 recently overheated. It now has a rough idle when I start it, which disappears almost completely once I drive it a bit and it gets warmed up. What could be the issue?

Welcome to Motor Vehicle Maintenance & Repair! Are there any codes present? (Check engine light on?) If so, what are they?– Pᴀᴜʟsᴛᴇʀ2 ♦Dec 27, 2022 at 22:07

That's the weird part. After overheating I got a check engine light with codes showing misfires on 6 cylinders. I cleared that but it came back. Now it went off again (on it's own) and has been off for a couple days.– GeoDec 28, 2022 at 0:03

Is it still missing when cold?– Pᴀᴜʟsᴛᴇʀ2 ♦Dec 28, 2022 at 0:07

Yes, but with no engine light coming on.– GeoDec 28, 2022 at 0:08

When it overheated, how hot did it get? What exactly happened when it overheated? Have you checked the coolant levels? When you start it up, do you see excess smoke/steam from the exhaust?– Pᴀᴜʟsᴛᴇʀ2 ♦Dec 28, 2022 at 0:12
