you should have a waxstat on the back of the throttle body, connected to a quadrant that holds the throttle open when cold, maybe it,s stuck ?

thank you for the very quick reply.. do you have a pic on the specific part sir? ill give it a try..

most mechanics here are clueless on micras since its an import car.. and nissan garage asks for $50US(converted) just for a checkup excluding repair..so ill go DIY for now..

the waxstat is in the middle, and pushes up (or down) to give a fast idle when cold

is this the one in red sir? if so how do i clean it?
yes i noticed RPM does not raise like before when cold start..

thanks in advance

yes, but i think it,s factory fitted, and not serviceable, but you may be able to free it off if its seized tho

frank

ouch.. so i guess my last option is to find another throttle body..
do you have any recommended sites to get one sir?

thanks

check if it moves position from cold to hot first, and if not, try some thin oil on it overnight, then some gentle leverage

frank

 

[CMF_Akinari]

frank

it does not move sir.. ill try the thin oil fix you suggested..
ill inform you the results asap..

thank you

update on the fix..

i removed the throttle body and checked on the waxstat.. it was stuck and had to use a little thin oil to loosen it up suggested by sir frank.. will be checking tomorrow morning from cold start..

@frank

sir is the waxstat on pull(down) position if throttle body unmounted?
or should it be on push(up) position?

thnx

aki

 

[CMF_frank2]

sir aki

it looks to me like, up for off (no fast idle/hot)
and down for fast idle

frank

 

[CMF_Akinari]

frank

ok thank you sir.. will be checking the results this morning from cold start..

aki

omg problem is back.. engine is stalling from cold start again..
i noticed the waxstat only gives the engine a little more rpm for a couple of mins and it starts to open and brings the rpm down to normal even though the engine still isnt hot enough..
