fuel trim malfunction
 
ok so i just bought a 98 honda civic lx and thought everything was great until the check engine light came on. the code that came up was a fuel trim malfunction. i went ahead and had the spark plugs and wires, the fuel pressure regulator and had a fuel injection service done. i used the 44k stuff as well. it is still there. car sounds like its running good and not having any trouble with it at all. it has been in a front end collision and they replaced the exhaust, oil pan, and three struts before i bought it. i can't seem to find the problem. any ideas?
