11/95 M42 ICV?

[Michael_M]

I've been looking all over the place for the location of the ICV in my M42 11/95 production but I couldn't find it. just wanted to clean it to give me smoother idle.. Currently no issues with idle except when starting the car in cold it feels like it is misfiring for the first 30sec. and then runs normally. only happens when temperature outside drops to -3 or something!

And I have a knocking sound coming from the intake side when the car is cold but once it is warm it is smooth enough other than some rattling and whinning noise from the pulleys which is understandable as the car is old and it has 262k on its original engine. you can't really cure everything for engine that old!

Regarding ICV, tried to search the forum most ICV Clean up guides they didn't mention what year was their ti, searched realoem and surprisingly they have the drawing for it but when you go for description is it mentioned parts are not available for this car, check another parts website exactly like realoem and it wasn't even there.. any ideas for both issues?

Currently I'm reading some articles form another forum members regarding cold idle issues but I have just replaced the coil pack, inspected spark plug wires, replaced the spark plugs along the cooling system overhauling.. I had those noises even before I do all that still replacing the spark plugs cured the the cold start issues for a while and now it is back but still better than before!

11/95 is likely one of those M42/M44 hybrids that may have some M42 parts and some M44 parts. Look closely around where the throttle body is- an M44 looks like this:



the larger of the two black plastic components (the one to the right) attached to the throttle body is the ICV for later engines.

If your throttle body looks like this:



Then you have the earlier (M42) throttle body and the ICV is a metal, cylindrical component located underneath the intake manifold (much more of a PITA to get to and replace).



The M44 ICV is a piece of cake to replace/clean (10 minute job, max!). The M42 is a much more involved project; there is a good write up on cleaning/replacing the M42 ICV here.
