They do idle a bit high when cold anyway but shouldn't be trying to race away. First two ports of call would be iacv and vacuum pipes, especially the T section under the engine cover which is common for breaking apart.

Don't take Mr. Previous Owner's word for it, take it to pieces and check that the parts look as if they've been recently fitted. While you're at it, inspect the electrical connector closely to make sure that the terminals are clean and a good fit. Simon

Update removed the idle valve and gave it a clean replaced gasket and seal and rpm have dropped from 1500 to 1100 when cold so all good must of been sucking air into valve,Was really prity clean inside so im thinking the gasket or seal was my culprit.
Cheers everybody for the help appreciated. julian
