E36 M40 ICV Needed

[olygopoly]

Hi guys,Anyone knows where i can find a good & cheap ICV for my engine. The other day, i tried to change my AFM but the problem still occurs. The mechanis suspect that maybe the ICV is causing the problem.What happen is that, the car is OK when in 'N' or 'P' gear. But once in 'D' gear, the car start to jerk and sometimes causing the engine go dead. Beside dat the engine kindda of shaking and we can hear the engine is not running smoothly.

well try to unplug the ICV and see if the engine stalls or still running ...

as i know if the engine stalls ..then the ICV is OK ..or else time to change ..

if car is jerking it may come from the AFM ... i went trough the same and upon changing the AFM ..problem dissapear ...

try to interchange first before you decide ..

thanks bro iceman for the tips.
well the mechanic did unplug the cable and the engine is still running. any suggestion why ? the engine doesnt sound smoothly. one of the mechanic said it sounds like mis-firing. havent check on that

 

[ICEMAN 68]

did the mech unplug the AFM or ICV ?? cuz sometimes they unplug the AFM rather than icv ...

What's the millage on ya machine right now ?

 

[olygopoly]

the mech unplug the ICV cable. not the AFM. mileage think roughly 250k

Never use WD40 to clean ICV. Please use carburator/injection cleaner as they evaporates and thinner than WD40. as for your case it should be the AFM, but the mechanic confirmed itz not. As for ICV, failing ICV should be detected even before you engage to "D". And yes the engine would be jerking(batuk-batuk). Perhaps you should get 2nd opinion at another workshop. Gud luck

check the following as well:-

1. fuel filter
2. spark plug
3. Ignition HT cables.
4. spark plug cables connectors.
5. Vacuum hoses
6. AFM

You can do a quick check on the AFM by removing the air filter and afm. check whether the vane is stuck or not.

btw, if the problem is with the ICV, you can do a quick check by ON-OFF the aircon. see whether difference in the idling RPM. What is your idling rpm? It might help to know it.

thanks guy for the response. well my idling rpm currently i guess is roughly around 700-800. b4 dis it is 1k or slightly more than that adn during this state the car wont jerk but the engine sound loud la.

a specialist said that e36 m40 should be at 800 and when turn ON aircond, drop to 700. well when turn ON the aircond, the rpm i guess drop slightly but sumtime cannot see the diff.

Based on the above, I think your ICV is OK. Check the vaccum hose first.

 

[ICEMAN 68]

Bro if can try cleaning or perhaps servicing your throttle BODY and change the BOOT hose thats connected for the TB to the AFM ...

maybe the BOOT hose is leaking as due to heat or long time no change ....

Thanks jarance. Will try to check the vacum hose then

Try using the forum search "tag" function. eg.. search "TAG" AFM or ICV.

The above subjects have been discussed in detail several times. :rock:
