Hello,
I have a very strange ICV Behavior with my m102, Car starts directly and no running problems at all no stalls either.
The problem is when I start the car in the morning I don't have that Idle Raise that should happen for some seconds on cold start and it starts just fine with the normal Idle 750RPM. no stalls and no idle fluctuation after giving it gas either.
The funny thing is sometimes and especially on sudden weather and temp changes it acts normally and has the idle up thing and even when the car is hot.
I traced the wiring from ICV to OVP and from ICV to ECU. in order to find any bad contact if any but I couldn't find anything wrong. the ICV Pin 1 is getting +12v from the OVP and the other Pin is getting ground from ECU.
the voltage between pin 1 and battery ground is 13.5.
The voltage between pins 1 and 2 is around 5.45v when the engine is running.
if I disconnect the ICV while the engine is running I have a slight increase in idle which should be a good sign.
I cleaned the ICV once by soaking it for 1 hour in carb cleaner and it acted nicely for just 2 days and back to usual.
The question is: does it needs more cleaning or it is a bad sticking ICV and needs replacement?
It is not causing any driving reliability that s why I m frustrated if it is a bad one or not. could it be somehow mechanically damaged and locked to a certain position preventing it from opening further?
