Bad idle

[Tigerhorns]

I have a video i made put it on youtube, and here is the link. YouTube - 91 Eagle Talon Tsi rough idle

If you see the video on youtube itself in the description i have alot of info on the car.

just wanna throw in there when i am on a hill, and i start my car i have to hold the brake, and give it a little gas to keep it from stalling out until it hits even ground.

is that your new motor? well have you gave it a boost leak test... and if its not the new motor... when did it sart and how did it happen if you know?

 

[Tigerhorns]

No this is not a rebuild i have done a full tune up on it so far, but not a boost leak test i know i need to do that >< i will soon, but they want 80 dollars to smoke my car out im thinking its some kind of problem with my throttle body to be honest, but then again i am here asking for help .

 

[BLINKY619]

how did it start? when did it start?

 

[Tigerhorns]

Give me 40 more mins i will post a video of the car driving today.

 

[BLINKY619]

same question again,,,!!! how did it start? and when did it happen? what were you doing when it happened?

 

[Tigerhorns]

When i first got this car it ran like crap smoked squeaked all that crap busted motor mounts leaking valve cover cracked tires nasty fuel filter some old damn v8 lookin fuel pump it was huge looked like a coffee mug. anyways your catching my point.

Since im such a newb i looked at http://www.dsmtuners.com/forums/frequently-answered-dsm-questions/239375-maintenance-schedule.html did that added some bigger injectors bigger fuel pump boost controler and all that. went picked the car up from the guy ya ran so much better then when i droped it off, but it stalled now, and had a bit of a idle problem.

I wanna throw in there that my gas pedal is a little hard to push in sometimes but once it moves it gets really easy to push up and down if you know what i mean dont really know if that makes much sense

 

[BLINKY619]

ok im kind of confused on what you said... you got the car from someone and it started idling bad? or whats up with the story..... sorry man i just dont understand half of what your saying...!!! and has the car had this problem since you got it?

No the car started stalling out after i put the fuel pump and injectors and mas in it


the car was smoking, and sputtering when i got it

so your saying your boost is lower than normal? if so you gotta check for vacuum and boost leaks...!!!! and was tha a WOT pull?

 

[Tigerhorns]

ya that was wot i turned the boost down to what ever its at now it wont go any higher then 8

 

[BLINKY619]

oh man seems like you have a major boost leak or may have blowna coupler.... why dont you give it a boost leak test? also you may consider trying this... start your car up and let it idle... now go to your motor and remove/unplug the mas and see if it changes anything? have you checked what your tps is set to...!!

 

[Tigerhorns]

How would i go about doing that?

 

[gofer]

How did you wire up your SAFC exactly and what are your Hi Thrtl & Lo Thrtl settings?

 

[Tigerhorns]

My SAFC is sitting in the trunk of my car i was told to wait for my wideband it will be here tomorrow, and im not going to lie i am kinda scared about hooking it up

I have this though it looks easy, but this is a area i know nothing about http://www.vfaq.com/mods/gvr4_afc_instructions.html

I allso wanna say when i got the car i changed the oil, and put the el cheap o in 10-40w plan on changing it when the car hits 1000 miles after me owning it just trying to get all the poop out my motor, is this oil good for the car?

 

[gofer]

Your upgrade path has been a bit backwards and could be causing more problems than anything else. You should never install bigger injectors without an SAFC or a fuel controller of some sort, your car being an A/T just amplifies the problem. The ECU assumes your car is equipped with 390cc injectors but in reality you've installed 550cc injectors which are flowing 29% more fuel. Until you get that SAFC installed your going to be having idle problems, cruise problems, and WOT problems. Installing the wideband will only help WOT tuning but getting that SAFC installed NOW will let you compensate for those bigger injectors.

 

[Tigerhorns]

The thing is i dont know the first thing about using that thing. Say if i used the diagram above, and i managed to make it work what would i do then, because i have never used one.

I mean how hard is it to install it?

Do you think just anyone could do this?

 

[gofer]

Before I go any further ALL CARS ARE DIFFERENT so these settings are to just get you in the ballpark with your SAFC settings.

-Lo Thrtl-
1k -6 2k -8 3k -10 4k -12 5k -12 6k -12 7k -12
-Hi Thrtl-
1k -29 2k -29 3k -29 4k -29 5k -29 6k -29 7k -29
-TH Point-
Lo 30% Hi 80%​

Did I mention ALL cars are different? The only way to know for sure is by using a wideband and a logger.

 

[Tigerhorns]

Are you saying i should wait until i get my wideband, and logger before doing this, or are you saying give these numbers a shot while waiting.

and does this diagram for the SAFC installation look correct for my year car and all that. APEX'i AFC installation for the Galant VR4

something else i wanna say too my bov is teed from the pcv valve then it it is connected again right over the valve cover if you look youll see a little bit of white in that black vacum line do you think that could be a problem too?

I'm saying your having problems because your running bigger injectors and aren't compesating for them. It's your car so what you do is up to you, waiting for a wideband and logger is probably a good idea.

If it were my car I'd install the SAFC and input those settings since the 550's are already installed.

I'm on my iPhone and can't look at wiring diagrams too easily to verify that write up. I'll look at it when I get home I'll make sure it's right...

 

[Tigerhorns]

allright well when i hear back from you is when ill hook it up allso something else i wanna say too my bov is teed from the pcv valve then it it is connected again right over the valve cover if you look youll see a little bit of white in that black vacum line do you think that could be a problem too? the fact that it just doesnt have its own line?

 

[VETTE_50_TH]

You have some extremely low oil pressure.

 

[Tigerhorns]

I put 10-40w el cheapo in it was on sale just was trying to run that for like 1000 miles to get rid of all the junk. i checked my oil like 2 days ago it was good and very clean. I put bp 93 and lucas injector cleaner in

 

[gofer]

Dude your 1gs all jacked up, your bov line should go directly from the bov to the intake manifold no tee's into anything.

 

[Tigerhorns]

see and thats what i thought, but the guy who did the work on my car said it was ok told me i had a non turbo air intake manifold, and there was no nipple for him to put it into on there.
