In need of suggestions.

I recently got into a minor car accident, where the left fender, radiator, and bumper took some damage (mainly cosmetics for bumper and fender), upon replacing the radiator, i noticed that the car had began idiling at very low rpms, and is making more of a deeper sound now..Also, to note that i have not drove it really since i replaced it, as i had to go to work shortly after..
 
Any suggestions on what i should do or look for?
 
Thanks guys i appreciate it.

Tell us what year trim car for starters.
 
good luck

we''ll it''s a 91 lx, but doesn''t matter now, thanks anyways.

Did you figure out the problem?
