esfand,

Tony is from Nissan Dealer..... so he will have the access to it... and tell you the truth... as I know, no one can get/buy a Consult tool at all from Nissan if you aren't an authorised Nissan dealer.

cheers,

richie

It says to hook that vacuum line to the crank case breather hose . I have my breather hose dangling and not hooked up to the intake . [Vortech SC] Would this mod be useless since the breather hose is not hooked up to the intake ?

booger,

I think you just need to connect the breather hose to the vacuum line, therefore you don't need to have the T end at the breather end I GUESS, just a L shape connector will do... because we are using the breather hose to create vacuum here since it sucks air down to the crank case... I might be wrong here, if I am, someone please correct me.

cheers,

richie

I am not sure if the hose needs to be connected to the intake or not, to provide sufficient vacuum. I would say yes, only in the thinking that you need the air to flow through the hose to create an open vacuum. Not too certain, I've never tried without, so.......?

I don't see why it would hurt.. but I'd leave it alone.

The cammed cars' idle problem is more of a concern.

I agree, you can try it on a non-cammed car, it would work but i'm not exactly what the car would idle like etc... with this mod on a non-cammed car. You aren't having the vacuum problems of a cammed car, so...... anyone wish to try?

no, i do not think that this has bearing on AF ratios, this is just a trick to get more vacum to keep the idle normal, i do not see how this would increase the air going into the motor much at all during driving conditions. when we checked my plugs, they were burning perfect, not too lean not too rich, (although that isn't the decisive way or the 100% correct way of checking for a too lean condition), so i expect that it wouldn't affect the AF ratio in a negative way...

If this affected A/F there would already be the Cold Air Vacuum Hose product

I take it you're having idleing issues? I anxiously await your findings!

hey everyone,

i do not have cams installed on my car, but my idle seemed a bit rocky and low so i figured i'd try this out considering that if this didn't work well i could just replace the tees with a straight splice piece.

the install was extremely short. the only thing that took long was taking off my intake tube so i could access the breater hose. after installation i checked for leaks...none. watched my idle presistantly and it was def a lot higher. after warming up to normal temps, the idle stayed sturdy around 800-850. perfect!

took it for a few wot runs on the bypass ramps by me and no problems what so ever UNTIL around a half hour later my 'service engine soon' light came on. luckly, advanced autoparts has an odbII scanner so i had them get the code. it came out as 'idle system rpm high' code. ok i thought this isn't that bad. i can just reset the ecu and the light will go away.

i go back to my house and reset the ecu via technosquare method...no luck the light still comes on...

i drove a total of 400 miles this weekend up to watkins glen and back to philly with no problems whatsoever with the engine, oil pressure, temp, etc...so i know this is not an extremely terrible problem.

but, is there a way i can get the ecu to learn the new idle and deal with it rather than throw a code? i guess i could always go out a buy some cams right?!?

Like i've said, we have not tested this idle kit on cars not running cams, but it seems as if it took care of the problem more or less....
See on my car, I've got everything done, so with that said, i expect check lights to come on with me, jsut as long as the car doesn't stall, and it runs fine, that's all i care about. I can't remember if that code is one of the two i was throwing, but i think so, that coupled with a generic random cylinder misfire which is pretty synonamous with cams on 04s.
Seems like the kit can work both ways though

why doesn't the guy with a rough idle just get his idle adjusted at the dealer. Like Tony said, this is for cars where the idle adjustment just isn't enough

I am not sure if there is a way to clear that code and still use this kit. It's all dependant on the situation that the light comes on i would presume.

Any pictures of this installed? I looked at the diagrams over and over, and don't know where the 5/8" barb T's into. It says into the crankcase breather? Is that the hose next to the brake booster coming from the intake manifold? Is this the same hose that you splice into for an oil catch can?

Thanks

Alright, I did it. A few observations:

1. Made my idle rougher
2. The car would just die intermittantly, even if it had a great idle

Needless to say, I removed it.

I do have the APS TT installed, not sure if that makes any difference.

Does this only work if the idle was raised via ECU re-flash or consult reprogram?
