Rough idle after startup

A new symptom I’ve all the sudden started experiencing with my tundra is here and there when I start the truck up, whether I just drove it or not, the rpm goes up a little above 1 then comes down below 1 and has a rough idle for a few seconds before returning to idle.
I know it could be so many causes.
Spark plugs have about 30k on them currently, I do have a 4 year old battery in the truck.
I just changed the radiator and while doing so I cleaned all my air intake stuff, took the throttle body out and did a full clean, cleaned my k and n, and lastly cleaned the maf.
I have yet to see the results of what I did as I’m not able to drive it for a few days.
But I wanted to ask if anyone has experienced like symptoms and what was the cure?
Thanks in advance, yall rock!

 

Likely with something to do with you cleaning the air intake and associated parts. Make sure there are no vacuum leaks or cracks.

 

I don’t think you read what I posted correct.
This symptom was occurring before I cleaned everything.

I haven’t fully tested it with everything cleaned yet

 

Ok. Sorry. It was a little confusing. I had something similar on my 97LX450 and I had to readjust the throttle cable. The issue just came out of the blue.

 

I will look into this, thank you
