I have a 99 Focus 2L Ghia ...yeaterday it developed a fault , when i pulled upto a junction it revved up to 4k revs and didnt drop ...When i got home i noticed the Purge valve pipe had split and was really brittle so got another one today as i thought it would be that ..However again tonight it has done the same thing , However as soon as i depress the clutch pedal the revs drop to near normal ...Thoughts please ???

Idle control valve, EGR valve, MAF Sensor, they would be the first places to start? do you have the old trip computer? can you do the check for DTC codes?
