406 problem after ignition for your urgent help

[jonasy]

hi, all,
my 406(essence/2001/RFV/2.0/70,000KM)

after a long time(or not too short)flameout, every time after the ignition, the idle speed is always lower then its normal level(fast idle or speed up idle?),the idle indicator swings and engine shakes harshly for 10-15s, then idle speed goes up to normal and engine stops shake. Sometimes the engine will turn ignition off immediately under a little lower temp. (20c) even now in summer, but it can be easy to turn on again.

Having changed new idling motor and fuel filter, air filter, spark plugs, and cleaned throttle body, tank, fuel pump, water temp. sensor. checked air leak. they made without good result.

help me please.

there is a another doubt, for my this ride, when not running, its idle speed indicator always swings lightly even when it was new, why?

There is another sensor which was not mentioned here that would display a similar symptom. MAP ( Manifold Absolute pressure Sensor ). It is located just below the intake manifold and it is secured by a screw.

hope that helps
