2003 TAHOE reduced engine power ?

[Fj60+]

My girlfriend has a 2003 Tahoe, on the message panel a couple of days ago i got a low coolant level so i put coolant in it, after that the message went away and the check engine light went off. Today i got in the car and was driving up the hill to my house and i got a reduced engine power read-out, i check the coolant level again and it was a normal. She wrecked the truck about a month a ago and we just got it back a week ago, they replaced the radiator and the computer so i don't know what it could be, ill take it to Auto-Zone to get the error codes and report back with them.
Thanks.
