Got the code pulled at Autozone and it is "High RPM at Idle" Anyone know what could cause this and any possible solutions? I tested out my new NX wet kit nitrous out yest. for the first time and it was fine until later in the day....that's when it threw the SES light on. I'm idling at 900 compared to 650 now. Thanks.

 

Bump........

 

i have a 2000 se and mine idles all over, bad coil(s) but it's rough idle from 1100 down to 250 and holding for a minute or less

 

It's weird cuz if I do an ECU reset and the idle control valve reset, the RPM's return back to normal but as soon as I shut the engine down then back on it'll throw the SES light with the high RPM again. I can't find any vacuum leaks either. I prefer not to bring it into the dealer if I can help it.

 

try that trick that makes the ses light come on at autozone and they'll read or odb and tell you what it means. autozone reads it for free, if you don't have one find a place that will

 

whoops, nevermind that post... hehe, blushing

 

So noone else has had this problem before?

 

What year is yours?

If it's a 2002/2003 did you clean your throttle body recently?

 

Have same problem, found out today. WTH does it mean?
Clean throttle body a week ago. Changed all coils and sensors 3 weeks ago.
WTF?

 

My car is a 2002 6 speed. I haven't tried cleaning the throttle body yet but I was planning on doing that next as well. I was able to reset the SES light last night and so far it's still off but I have a feeling it may come back soon since the RPM's are still hovering around 900. I'm gonna have to check into the vacuum system again and see if the PCV valve is working right. Engine mods I have are PR CAI and NX wet kit.
