I did the TB mod awhile back. I'm wondering if this is the same for everyone else. It does this no matter what the weather is like, but worse in cold. When I start it up first time in the day, and after sitting for most of the day, if I don't keep my foot on the gas, it shuts off. It seems like I have to do this for at least a solid minute, and that's in hot weather. Does your car have the TB mod, and shut off when not warmed up?



Also, my defrost vents don't line up with the holes in the dash. I removed my dash awhile back, but I don't remember how things are attached back there. Do I have to remove my dash to get them to line up?

dash removal=bad

 

used to happen in my gxl.

i think it was a small vacuum leak if i remember correctly.

 

Yeah i have to hold the gas for about 30 seconds on my car.



Also baldy your postcount is exactly at 1337 after this post.

 

after i did the tb mod , it won't idle when cold.

 

mine shuts off when cold then holds perfect idel when warm but then again my preassure sensor is disconected and the nipple where it should be is sucking in air. I have a forced vacume leak to keep my car at a perfect idel.

 

Mine won't hold idle either until after about 5 minutes..but probably cuz i've got more issues then most of u



I'm in the market for a stock s5 TB btw....just to swap mine out and see what happens...

 

my engine will idle in cold but runs like complete *** for about 20 secs when on start up and has a low idle when cold, but when it warms up it goes up..

 

everyones car is like that with the tb mod. Most cars will barely idle, and then the first time you stop the car if you dont put on the gas it will die. After you start it up the second time, it will run like a champ

 

Hmm... that's interesting... because it just occured to me today that something about doing the TB mod might have something to do with why my TII wont idle. I have a freshly built and streetported s4 turbo motor that will not idle. It needs a little throttle fluttering to get it running, and when it's running, it seems to run perfectly fine, but it just will not idle. It doesn't even try. I've let it warm up for 15 minutes with my foot on the gas holding it at 1000rpm, and as soon as I let off the pedal, it dies just as it does when cold.



Although, I still have to fiddle around with some of the vacuum lines and crap, but now it does seem like the TB mod might have a lot to do with the non-idling problem.

 

that sounds more like a vacuum leak. My idle problem is only until it warms up, which now seems to be the norm. After warming up, it should idle.
