kill story and a vac leak problem
 

i finally got my first race since my crx got it's turbo.
it was a friend of mine with an MR2 250whp that runs a low 8 in the 8th mile
we did a freeway run from 60ish by the time i got into 4th gear i was quite a few cars ahead of him.
we did 4 runs, on the last one i just dropped 4th and he pulled about a fender from me then i flew past him.
i need to get a video for you nogs. i'd take it to the track, but i have blown out shocks wrapped in ebay coilovers and crappy tires. so 1-2nd gear is nothing but spin.
i've been having a problem with my charge pipes blowing off so i took them off today and flared out the ends. they held fine for the races so that was good.

however i do have a vac leak. when i'm at idle the rpms bounce from 500-1500 over and over.
is there a hmt way to find the leak?
if i had a boost leak in my charge pipes would that cause a vac leak? or is it like a normal n/a vac leak?
just wanted to post this for you nogs.

check and clean your idle air control valve 9 times out of 10 thats what it is

Re: kill story and a vac leak problem
 

i think it is called the fit valve in the throttle body tighten that bitch up my car did it forever

Re: kill story and a vac leak problem
 

To check for a vac leak in charge piping, use soapy water and look for air bubbles.

Re: kill story and a vac leak problem
 

but thats not what is causing is problem...spray some brake cleaner or starting fluid/carb cleaner around where you suspect a leak. First thing i would mess with is the idle screw on the TB

Re: kill story and a vac leak problem
 

Yea its that wax plunger jobby right at the TB. I had the same issue. Tighten that bitch up and your good to go.

Re: kill story and a vac leak problem
 

i forgot to say that the rpms only do that when the motor is warmed up.

Re: kill story and a vac leak problem
 

IACV then, I believe.

Re: kill story and a vac leak problem
 

i'm gonna check the idle screw to see how the o-ring looks then i'm gonna pull the iacv. if it's none of those how do i find the leak with carb cleaner.

also can i pull the vac lines for all the ---- that is on the fire wall? i know the map sensor is there, but what else has to stay?
here is a pic of what i'm talking about.

Re: kill story and a vac leak problem
 

I have a similar problem with my sol right now. Try the iacv first, and look over all your vacuum lines for cracks, decay, std's, ect. I ziptie all my vacuum lines on just for peace of mind. In my case, I also suspect an electrical problem in the weird idle, as the previous owner relocated the battery and did the engine swap, and he was a retard. So when I have time, I'm going to clean the iacv, go over my ground wires, and probably add a few more for good measure. I expect that to fix my idle. Give it a whirl

Re: kill story and a vac leak problem
 

code 9s do that as well it was annoying as ----. O0

Re: kill story and a vac leak problem
 

what is code 9? I failed my course in memorizing all the honda cel's

Re: kill story and a vac leak problem
 

code 9 is cylinder position..

Re: kill story and a vac leak problem
 

yeah i'm not getting any codes, thank god...
i didn't have time today to pull the iacv so it's gonna have to wait till tomorrow

Re: kill story and a vac leak problem
 

take something (like carb cleaner) that is more volatile than gasoline and spray it everywhere a vacuum leak could be (intake to head, tb to intake, trace all vacuum lines with it, etc... you will know when you find the leak (if you have one) as the motor will rev a little higher than normal (it is enough that it is obvious).
