It's normal for the car to idle higher when it first starts up. Upon initial startup is it idling really really high? Play around with your idle adj screw...

 

I have an idea: read a book.

alright cool thanks i'll check that out should i just look for air leak or somthing on the manifold ?

 

any other idea's

 

If your idle is jumping up and down 9 times out of 10 its a vacuum leak or a dirty iacv, clean that, check for leaks and you will probably find your problem.

yeah probly a vacuum leak on the idle sensor if u still have the stock intake manifold it has a little idle sensor. its attached to the throttle cable and throttle body.

i dont have the stock manifold i have an ITR

 

if you know anyone that has a smoke machine, try plugging it up, it will show you exasctly where your vaccum leak is, if indeed you have one. otherwise check your iacv.

 

is there a type of cleaner i can buy for my IACV that u guys know about or how do u guys do it ?

 

brake cleaner

forsure thanks jimmy

 

i think i figured urs out i worked on mine all day cleaning the intake with some cleaner put it all back to gether n it was idling up n down when it warmed up at bout 1000-1500rpms i pulled my main fuse thats on my battery to reset the (programed feul injection) hit me back if u got a chance take a look at what i posted about my 89 integra with a b16

 

can u post the link for that ..my car doesnt idle high it idle's low and then just turns off ?

 

 

anyone else ?

 

get a helms

 

anyone got any idea's ?

 

Have you tried any of the suggestions?

Idle screw? Brake cleaner to clean out IACV? Feel for leaks/fog machine for leaks on vacuum hoses? Reset ECU? Timing?

More time under the hood &gt; more time on the internet
