Question about 2005 Peugeot 405
I have a problem with my Peugeot 406 2.0L (2001 model). The engine starts fine but immediately dips down to below 500rpm and nearly stalls. Then it bounces back up to idle speed and after a second dips back down again. When I drive its fine above 2000 revs but as soon as it drops under it starts to stall, then when I get above 2000rpm again its ok. Kinda jerky to drive!
Check the idle air control valve.
the air control valve is the little solid black plastic section on the air filter box to the large pipe its got a plug on it for the wiring the valve is a small blade inside.
An idle air control valve (iac) allows the flow of air into the intake to be mixed with fuel while the vehicle is at an idle. when you open the throttle the valve does not need to work because the air is coming from the air box hence the name idle air control .
its advisable to get car scanned at diagnosis center to get error codes, At diagnosis center you will receive the error code.As per
the error code it will detect the exact faulty part in the car due to which the
problem is occurring.For more help :--- at www.autozone.com its absolutely free

Well first thing you need to do is get it hooked to a scan tool and find out what error codes are present....without any code information, and from what you describe i would say throttle position sensor, or a crankshaft or camshaft sensor is bad....but cant say for sure with no code data.
