hi can anyone point me i correct direction?
my 03 1.6 zetec 1.6 se has just passed mot n no more due to high idle fault
when the revs are increased to 3000rpm it falls back to 1500/2000 rpm

I have changed lamba,throttle position valve still no change

next option i thought was coil pack or idle control valve but do not want to keep throwing money for no cure,
any suggestions appreciated
