Struggling at startup

[eosandov]

Hey guys I have a 2000 runner with 93K miles, a couple of days ago the truck started to struggle when starting up like if the battery was dying. I cleaned the posts cause they had corrosion, but that did not help much. I don't think is the battery because the truck is still running, I have not check the charge thou. Any body has had this issue? any suggestions? Thx
