you can start by talking in english.

check your throttle cable... it may be over tightened...

 

[Import2Vision]

Could be ur Idle screw.

 

[jdmlude]

Check the butterfly in the throttle body, of it's clogged it'll idle high.

k, i checked the throttle cable... was slightly tight. changed the map sensor and tps. now she idles at 2500-2700 when cold. when its warm the idle is inconsistent, it may idle at 800, sometimes as low as 600 then there are times when it will idle at 2500 when warm. thing is ... well its hard to explain, ...when i come out of gear and let it idle it will pick an idle and sit there...idle will not fluctuate (sp?). but the idle is, once again, inconsistent... BTW WHAT IS NORMAL IDLE ON A 5 SPEED D16Z6? thanks guys for the tips!!

normal idle on my 93 si was around 750 r you seeing n e trouble codes on your ecu thats the first thing you should check out it could be an engine coolant sesnor or your o2 sensors but check your ecu first if you dont know how reply to this reply

The idle on my '94 Civic EX D16Z is tuned to about 650.

i'm clueless on how to check the trouble codes on my ecu...please help

4,500 RPM's!!!!!!!!!!

That is high as hell! Over half-way to red line in my car

 

[si92hb]

I believe my manual says ideal rpm for d16z6 is 800-1100

check for vauum leaks as well..like in capped vacuum lines and stuff

 

[epic_race]

my 5sped ex idled at around 4grand!!!

 

[DAFeLUNG]

check the IACV or ICV

 

[JaySolSi]

Yeah I would say vaccum leak... When I installed my JRSC I had the same issue... I replaced all vaccum hoses with silicon ones, and my idle dropped, there was a few cracked lines and a few loose ones.

But make sure everything is connected to where is supposed to be.

i had the same prob.

first things is first. check for any vacuum leaks... then check if your coolant level is ok.. too low coolant will make your car idle hight to create pressure in the system.. then check your throttle cable to see if it is getting caught.... but this is what solved my cars problemm it may seem strange but it worked.... i changed the throttle cable rotor and the idle just dropped... i think it got fixed because the old throtle cable rotor used rubber bushings and they may have been getting stuck... i replaced it with the weapon r throttle rotor (also gives you quicker throttle response) and it fixed it... try it it was only $35 cdn...
