Cuore tick over/steering rack


Hi again .My daughters cuore 1.0 seems to hunt on tick over I raised the tick over up and it was better but then stayed high does this car have a idle valve which may need a clean when it was reved I could hear it drawing air but not at the air intake .It's first mess around with these cars so any help would be great .I managed to get the steering rack off and have sent it away for a rebuild.
