stalling

[esahuque]

yeah i know there are a few post out there with the same heading. I searched already.

Garrett T3/T04E TurboJGS manny and down pipeGodspeed E-GAY FMICCustom 2.5 IC piping555 InjectorsZ32 mafN1 3" catback with test pipeTurboxs BOV open.Enthalpy tuned ECU

its a new install and before i started the car ran fine. when i start it, it cranks right up, runs a little ruff but starts right up. idle fluxuates between 7.5 to about 9. when i give it a little gas it revs with no hesitation. but when i let off the gas (fast or slow) it dies. after it stalls it wont just crank back up, i have to give it gas while i turn it over to get i to start again unless you leave it sit a while then it will start right up again.

My MAF is on a 90 deg pipe, i closed the gap on my plugs from .35 to .30. checked for vac and ic piping leaks, couldn't find any. i did find a fuel leak on the rubber line underneath the fuel fllter and repaired it. EGR system not removed but blocked off with a JGS cap. Checked the timing and its where it should be. I do have an open bov which my ECU is tuned for and I completely removed it and plugged my holes after doing everything I stated above still no change in the idle or stalling problem. What else could it possiblely be?

Thanxs for any replies!

Yea recirculate your BOV will fix alot of your problems. Also how did you check for leaks?

[esahuque]

well, i would recirculate my BOV but its a turbosx type H RFL and if you haven't seen one before, it looks like a friggen airhorn. it cant be recirculated, no place to put the hose. also why when i removed the BOV off the IC piping did it still stall like when it was on the IC piping. is there any other way to test f its my BOV before i go and spend another 2 to 3 hundred on getting a new BOV, recirculating kit and welding.

[esahuque]

well i guess im going to have to buy a new bov and recirculate it but will doing that also fix my rough idle?

Unplug your BOV and tie the vacuum line in a knot so it doesn't leak.

I have a Greddy Type S that I will sell if you want it..

I know a lot of people here don't usually support the SAFC. But instead of buying a new bov you can pick up the SAFCI, and use the de cel settings on it so it will save you the hassle with recirculating a bov. And give you some extra options.

Now buying a new BoV and recirculating it, is the easiest option you have, because with the SAFC you have to wire it into your ecu and such. But if your are up to it you can learn something new .

[Chezedik]

Just recirc'd mine and made all of the difference. BTW, I hope that the correction works better than emanage, or you are just jerking off.

[extreme135]

i am running basically the same setup as you with a XS RFL open, I was having the same problem that i fixed easily, the springs in the XS are week and do not close all the way in Idle, especially after you rev it, take the top cap off of it pull out the spring, put 5-7 quarters or washers under the spring the same diameter, install cap, that sounds like your problem if you have not already tried this, fixed my problem like night and day, hope this helps.

[esahuque]

Yeah, noticed the same thing. Very week spring. i added 3 washers in it and it seemed to be to strong and sounded like i was getting compressor surge. so i have 2 in it right now it fixed the rough idle but it still stalls after i rev it. yesterday i ordered a new BOV, one that can be recirculate so after i recirculate it i will post and let yall know how it turned out.

What about leeky injectors, how do i test for that, i think ones a little lose and that could cause my problem too.

[extreme135]

If you are running the sidefeed injectors, where are you saying it is loose at, you should see it leaking where it goes into the fuel rail, unless you mean that it is leaking around the o-rings, which is very possible if you do not grease up the o-rings when installing them and make sure that you tightened the two screws on top a little bit at a time and evenly, but I had a leaky one a time ago after doing all of that, what I did was pulled the fuel rail off still connected to the fuel lines, vacuum does not have to be, put some rags or a towel with some paper bags or newspaper on top of them and put that underneath the fuel rail and injectors on the intake manifold, disconnect the lines to your distributor cap, turn the key over(not engine) just enough for the fuel pump to prime itself to the fuel rail, if there is any fuel under any of the injectors, then it is leaking, this can be either from the o-ring or the injector may be bad if it is shooting any gas out of the injector passage holes at bottom, found my problem twice by doing it this way, one time it was an o-ring and one time two bad injectors, also is your car smoking at all when it is idling, and have you checked or tryied adjusting your tps sensor, I have seen people before when puting there coupler on there intercooler piping where it meets the throttle body, when you put your t clamp you can very easily hit and move the tps out of place, which will mess up your idle, and also I just noticed in your pic that your maf sensor is too close to the turbo, it needs to be at least 12 inches away, when you rev your car and the turbo begins to spool and then you let off, the wheel on the turbo will send false readings to your maf which will the ecu will dump more fuel to componsate for which will make the engine stall or idle eratically.

[esahuque]

Yeah, i have side feed injectors. 3 of them are tight but one of them i can (not move up and down or side to side) twist very easly, untill the the conector hits the cap of course. No smoke though and my plugs are burning properly

And my MAF is now on a 90, 14" long

[adrianfromthecastle]

have you looked into getting the hks eids?http://www.hksusa.com/products/?id=2175

might help your idle problems

[esahuque]

how well does the hks eids work? I might have to try that out, THANX

[adrianfromthecastle]

personally I don't have it, well, cuz I'm still rockin the stock recirc valve...

But I've heard good reviews. Try it out and let me (us) know how well it works.

[esahuque]

OK, i recirculated my BOV and my MAF is on a 90 and 14" away from my turbo. Checked for any leaks and cleaned and tested my IACV. Its not stalling as easy as it was. Now i can rev it as much as i want, but when i come out of boost i have to leave it in gear until it goes under atleast 2500 rpm or it will stall. problem 2, Enthalpy tuned ECU and after moving my MAF Im still running rich. think it's a bad tune, should i get him to send me a new chip.

problem 3, tried to set my timimg and its set at 20 but it's very erratic, it will jump aroud by a few degrees. What would cause that?

[esahuque]

OK, I think I MAY have found my problem. Tried to do a boost leak test and the EGR crap is leaking, right out the valve. Going to pull my intake and DELETE all that s**t. also going to get rid of the charcoal canister, no need for it since the EGR is going to be taken out. Hope this solve's most, if not all my problems.

[esahuque]

Well, I'm at the end of my rope, about to just bump up my idle to 1000 rpm and call it a day. recirculeted my BOV, moved my MAF 14" away from my turbo. took of all my EGR crap along with all the vac line that went with it incluludind the charcole canster. and capped off the vac ports. did a boost leak test,cleaned and tested my IACV, all is good. And the DAMN thing is still killng when i push my clutch in. any other suggestions, I dont know whats left to do.

[esahuque]

I feel like i'm walking through a maze with my eyes cloesed. I think I know why its stalling, probably the same reason i'm fauling out spark plugs. i'm running stupid rich. My fuel pressure is at 39 at idle after worm up. Thats not right is it? It should be at 34 right?

I'm going to change my O2 senser.

I want to check and clean my MAF. Still searching on how to do that. Do i just follow my fsm or since i put a Z32 it should be tested differantly?

I think it could also be my Enthalpy tuned ECU is causing me to run rich. but before i ask him to send me a reflash i would like to go over every possible reason why i could be running rich.

What other things could cause me to run rich?

Thanks for any replys

[esahuque]

Anyone!

[GEO]

wait, why would people not support the safc? I love the thing! I was also going to suggest doing the de-cel on the safc as well, but notice you didn't have one.

[esahuque]

Not that I dont support it just haven't had the money to get it along with a wideband. I want one because i would like to run my open BOV anyway. Just wanted to fix any other problems i had before i went and made any adj with a SAFC. I had the motor checked out by a few loc and my motor is fine its in my Enthalpy tune. Its making me run super rich so now im about to order a SAFC and ALL my problems will go away.

[S13FX]

Make sure you get your self a wide band to go along with the SAFC.

Since you have a tuned ECU you don't have to really worry about timing.

Just remember homey, there is a saying that goes like this.

And Im one of them.

Yes i'm deff getting a wideband before adj anything, that should go without saying. Anyway thanks for everyones help on my first installation and walking me through any of the problems I've had. Yall have been a BIG help. NICO ROCKS
