got a car that has an idle drop only when the car comes to a complete stop...if the ac is on it goes from the normal 800ish to around 650ish...w/ out ac on it is from 750ish to around 510ish...it only does this sometimes and it doesn't stay down at those low idles for more than 30 seconds before it returns to normal..not throwin any codes and i'm really just completely clueless as to what it could be..any help would be greatly appreciated...

 

my B20 does that.. but that's just cause it comes from a richer fuel map to a leaner one at idle, causes the car to almost die...

ya i haven't really been too worried about it..i was just kinda wondering why cause its a little strange...

 

I have a gsr motor with skunk2 stage 2 cams on stock compression, my idle goes really low once it gets warmed up. I am running a hondata base map, that came with it, haven't gotten it tuned yet, cuz I am running the old hondata.

Is there anyway to tune out the weird low idle ?

 

i thought may be by adding a little fuel at 1000 rpms it'd help w/ my idle a bit but it didn't...not really too concerned since this motor will be gone w/ in the month but it just seems a lil strange.

 

Mine did that, replaced the IAC valve and it went away.

 

same **** as you guys do you have an aftermarket throttlebody also check the iac

 

how much for a b series IAC ?

 

ya i gotta type r throttle body...i'll try and replace the iac and see if it goes away...she's died a couple times lately so i think its time to assess the problem

 

let me know how it goes, i might do the same

 

Try cleaning your IAC first, that might be all it needs.

IAC's are $128.33 (b-series) plus shipping at Majestic Honda.

Look under throttle body.

what does IAC stand for?

 

I believe it is Idle Air Controll.
