well I am new to the integra seen and am wondering why my car is idling funny? I originally had no speedo so I replaced the speed sensor tonigh,t now speed works but car idles funny. When I drive it is fine but hen approaching a red light to brake car holds at 2k rpm's then finally drops to 1100. Do you think I knocked something loose? if so what? I need you help. thanks guys

 

check the plug for the IACV (Idle Air Control Valve)... you may have pulled on the harness and unplugged it... if that doesn't help your next step is to clean the IACV... what year integra do you have?

 

its a 94 where is the iac located in it I am used to nissans

 

It's located on the back of the intake manifold should be two 12mm's holding it on

 

I will check it out first thing in the morning thatns for your help how do I clean it btw

 

you can take it off and spray brake cleaner into it... after you do that make sure there's no breaks in the TB gasket... then with the car on spray brake cleaner into the smaller hole in the TB that leads to the IACV... I only say that because some people say it's better to clean it while it's functioning

 

ok sweet thanks

 

no problem man... post back if it fixes it

 

well today checked al vac lines and all appeared fine but I did notice that my silicone coupling was ripped that leads from intake to throttle body Could that be the cause?

 

do you have a picture?

 

to late tonight but I will take one tomI dont think the crack has anything to do with it bc there is no maf I think I just need to clean iac or maybe tb gettin stuck?

 

yeah clean the TB too... carbon build up is sometimes the culprit
