I just installed the Injen Cold air intake on my Z and it seems as if the idle is very low, at times it even begins to shake. I say its just above 500rpm. Any suggestions on how to fix it? Has anyone had this problem?

 

When you say 500rpm, do you mean 500 rpm or just halfway between 0 and 1k? Halfway is actually like 600-700rpm which is "normal".

I know what you are talking about though. My car stock did the same thing. With an AEM CAI it also did it. With the JWT it does it too. I don't think it has anything to do with the intakes

How was the idle before the install?

 

Dude, check if everything is sealed properly, the tubes and everything... that was my problem

 

I have JWT on mine for over 20K miles and ive never had any idle issues at all. Just like stock. The sound however....... =)

 

Check for vaccum leaks, if none give it couple hundred miles the ECU needs time to adjust airflow map. Good luck

 

+1

I second checking for vaccum leaks... A leak will cause an inconsistent idle and possibly stalling out. If idle remains low, I would have someone connect a consult to it and possibly bump the idle up. I have my timing advanced and the idle set to 800-850rpm...

 

yyea, ive had the JWT and UTR chrome pipe and no idle problem. It feels like it was stock and love the sound it gives off. Check ur install and u prolly have the vacuum loose.

 

Thanks for all the help, Ill check for leaks to see if thats the problem. I had the JWT pop charger on it before and the idle was great, no problems. But now it idles a good amount below normal. I also give it some time to see if it is the ECU needs to adjust. Once again thanks for all the help.

 

So nobody's idle fluctuates? It's rock solid and doesn't waver?

 

It was pretty solid before I instaled the Injen intake.
