Alright, I have no idea whats going on, but my rpm will drop 200-300rpm and then rise back up again to normal idle, it only does this once in a while when i m idling at a stop light. It doesn't happen often, but it annoys the crap out of me, i've changed my sparkplugs, cleaned my air filter, and my map sensor. I haven't changed the sparkplug wires yet, hope you guys can help.

 

Mine does that too. I guess its the idle control sensor. The only place I've found one is the Mitsu dealership and they are $313. I'm still looking for somewhere else to fine one.

 

Have you tried the EvoM forums here? I'd try talking to dealers here on the forums if the vendors can't get them. I've found the dealers online have better prices than the local shops most of the time.

 

what does the idle control sensor look like and where is it located?

 

Don't all IX's do that? Mine does that too, I'm almost used to it now. Although, I wish I could resolve it.

 

Same issue here...I've learned to live with it.

 

I haven't tried that yet, but I'm going to give it a shot now. I don't know if all the IX's do it, but my VIII does it too. I'm just sick of seeing that CEL.

 

same here!

 

What Intake do you have?

 

my viii does the same thing

 

Mine does it too.

 

Probably bov or intake pipe/filter related.
