Try resetting the throttle:
Without touching the throttle pedal through the process:
1) Turn on ignition for 90 secs
2) Turn off for 90 secs
3) Start engine and leave to idle for about 5 mins ... it will fluctuate and then should settle down to around 850rpm.
Stop, restart and take for a run.
It's often the Idle Actuator on the side if the throttle body (not helped if throttle is opened by hand), lambda or MAF.
