Peugeot 406 engine problem - 2.0L 2001 model

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!

Any idea's?

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 . Also then 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 its absolutely free to get car scanned. Thanks. keep updated for any more can rate this solution and show your appreciation.

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.

Btw, I’m available to help over the phone in case u need at

My 406 1.8liter engine has a tendency to shot down when in idle and cold. after 5 miles it runs fine.

Sounds as though it may be the Throttle Position Sensor. TPS. It is on e the throttle body and sets the idle of the engine.

Auto gearbox

if it has a dip stick under the bonnet you need to have the engine running with the box in neutral then dip the oil
if the engine is warm then it should read around the top mark, if the engine us cold then it should rear around the lower mark
if there is no dip stick then there is no way of checking the level and you will need to drain the box and re fill with the correct ammount through the gearbox breather on the top
