If it was O2 sensor or computer related the check engine light would come on. Start with replacing the fuel and air filters.
A bad coolant temperature sensor is one thing that could cause an idling speed problem with a Peugeot 406. There could also be a problem with the idle control valve.
The condenser fan is more likely to run when the car is idling. So if it NEVER comes on when idling you definitely have a problem. If the condenser is not cooled, then your compressor could get overloaded. It may be a problem with a relay that is preventing the fan from running - or some other issue.
I was told that this might be the EGR Valve either is clogged or going bad.
Check the throttle position sensor
blue smoke is normally related to fuel problem. there is so many things that could cause this that it is best to have it checked by a technician that you trust.
The idling speed cannot be adjusted for fuel injected models. It is done by the ECU depending on inputs from various sensors. If the idling is erratic it is best if the car is taken to the vauxhall dealership who have testing equipment called TECH 2 which diagnoses the problem.

550.00 @ Honda of Annapolis. Having the same problem with my 92 Accord.
try checking your cooloing fan. make sure it is running There is no air getting to your radiator as you are not moving! Or there is a problem elsewhere in your cooling system!
one of the main reasons an engine runs on or diesels can be related to the fact that it is idling too fast. Set the idling down and see if this imporoves
it maybe just a timing problem
answers are no where to be seen
probably the governor going bad
