I have a 2001 kio rio that i have owned for three weeks and have had nothing but problems. After replacing two trans mounts and an engine mount and the alternator now the check engine light is on. We had a friend look at it and he said it is an error code 455. Does anyone know what this means? Please help me.

It sounds to me like you have replaced everything except the most likely cause of your idle control problem...The Idle Air control. (IAC) (or Idle Speed Control Valve) It is located onthe throttle body and looks like the picture below.
need to run diagnostic codes, this will tell what the problem is, generally it will turn out to be a bad wheel sensor, and the diagnostics will point you to the right one. Once you not what code your getting check connectors at each when and then clear codes. If the same code is recorded again replace the wheel sensor indicated by diagnostics.
