Default Running Lean

I have a 98 GT and my check engine light came on. I had the codes checked....it's running lean in a couple ports. Is this a big deal and what do I do to fix it? Thanks for the help

please please fix it...running lean too long can make the combustion chambers over heat and well puts holes in ur pistions there fore like blowing your motor, have them look more in depth of whats the problem and fix it...

believe me, a guy around here did that with Forced Induction, blew his motor up on the highway because he ran lean and didnt want to fix it, FI or not lean conditions arent good,

I'll have to check on the codes again....this may sound stupid but I feel like he said port 2 maybe....or back left or something....I'm not positive, or sure that that even makes sense, but I'll check it out again for sure
