Dont know much about that car , found this on same car with same fault .Dont know if accurate or not .Could also check all air/ vac hoses .Changing engine coolant temp sensor worth a go .

" May be worth trying a manifold pressure sensor located on the underside of throttle body .Failing that it maybe wiring fault or engine ecu fault .The resyncronisation of the idle regulation motor needs doing on diagnostic equipment "
