99 limited running rich

[Klamath4R]

Hey all pretty new here, wondering if anyone can help. I put a cold air intake on my 99 and after a couple hours down the highway, I got a check engine light. It looks like the code is a fuel trim issue, and it's running rich. Any ideas on how to fix this?

Reset the EFI fuse.

is it at simple as clearing the codes or could it be a messed up sensor? I'll def start with the fuse... but what if the code comes back? the truck was running fine before I swapped the air intake, and I pretty gentle on it.

Find the EFI fuse in the fuse block under the hood and take it out for 30 mins.
