Does anyone know how to fix idle problem?
after i installed injen intake, my RPM dropped to 450~500, and it moves a lot. I posted this once and they said disconnect - battery so the ECU can relearn the mod. But for me this is not working. Does anyone can help me with this..???
oh i installed it one month ago and still have same problem.

 

would say get a ground kit....it would certainly lower ur rpm and smoother rev, also more stable too.

 

i have the exact same problem for 5 months now

 

I had the same problem with my Z for a month or two after I installed CAI. I installed a grounding kit and just drove the car around for a few weeks, and the problem stopped. I definitely have noticed that with the grounding kit, my car idles much smoother. I also think that it took my ECU/ECM a little time to get used to the mod. I origionally installed the CAI with about 2,500 miles on my car. I now have 12,000 miles and my car idles perfectly.
