hi guys...I've did a good amout of search and found vey usefull info but i'm still missing some.. here's the deal :

2000 itr with JDM b18c motor

The motor seem to idel some time to slow and other time way to fast ( 500 to 2000 rpm) but i does not bounce at first when the car start....

But as soon as I go into Vtec land.. the idel bounce from 500 to 1500...So what i'm doing for the time is to shut the car and restart it... So it stop bouncing....

I've been told by a friend that it is most likely (ok.... fenchi here.....I know the name in french but i got no clue on how it's call in english.... so here my direct translation) the sensor on the IM closer to the fiewall... motor slow down sensor....

Does that make sense?

If one of you guys could tell me the real name of that part....that would be great
