well it does it often but not all the time. it seems as if im cammed up or idleing at 250-350 rpm? it only does it when its warm out... idk wat it is. please help me out here.

 

When does it do it in relation to engine temp, does it do it when you start up or after you have been driving for a little while or both. Also does it hunt or jump around at all?

 

its jumps around because i have my system hittin. but when i mute it, it idles fine. or sumtimes i wont bump and itll still drop down to like 300rpm. i think it might be my battery but idk because it starts and all my electronics work fine(HIDs,system,Cluster,fogs,taillights) i might have little or no dimming in the cluster but thats it. and all this idling is when its hot.

 

well if it's not dimming when it goes down to 300 i want your alternator, but i doubt it is your battery that is pretty unlikely to affect idle. You still didn't answer the most important question to diagnose your problem, when does it do it after warmed up or before?

 

so it idles around 250-350 but only when its warm out?

 

only when its hot out or after driving for awhile. i think it may be my iacv.

 

yeah the things i can think of would be your iacv and also possibly your o2 sensor, For know focus on your iacv, when you are about to park your car next time with the engine still running and the idle jumping try unplugging the iacv and see what happens it should idle at 450 +- 50.

 

thanks ill try it.

 

doesnt do it.

 

just holds rpms at 500

 

so it is just sitting at 500 when you unplug the iacv cause that is what it should do. But are you saying you didn't notice any difference when you unplugged it because that could be indicating to you that your iacv is not functioning properly. Did you check the wiring, really you should clean the iacv either way it can never hurt.

i have the same issue... when the engine is in normal operating temp, and when i cranck up the audio then it starts to idle.. and also when i am driving with 100km/h and have the 5th gear in, the engine starts t idle at 2800 to 3000 rpm.. STRANGE!
