Default Car trying to stall out when I come to a stop...

I dont know what is goin on with my car, I just got it out of the dealer about 2 weeks ago after having the 'cold fuel leak' TSB done, and now I have a new problem. When starting the car, the idle quickly drops to almost 0 and then flys back up to 400~500. It drives fine, still pulling hard, no hesitations or anything. Shifting is smooth also, but when I come to a stop, the idle drops so low that it almost stalls, I can feel it knocking sometimes, then it climbs back up to normal.

Is it possible something wasnt connected when they put the manifold back in after the TSB? I havent even lifted the hood yet, it is freezing here again and my hood latch gets frozen in the cold and cant close it, so I can't really look under the hood till tommorow when the sun comes out. Does this point to the MAF, or could it be something like a weak battery? Hoses?

So many things wrong in the matter of a month

-- I guess I will also add that, my air filter did not get changed @ the 30,000 mile tune up, and the only mods on the car at the moment are an HKS Ti catback, and the gfb 50/50 bov. I plan on getting rid of the bov soon, it does nothing for me, but I have never had a problem with it. Could a dirty air filter cause this? I have a K&N filter attached to an AEM shortram I could swap in there to see if anything changes, I just want to avoid a trip to the dealer even though I am still under warrenty, they hold my car for so long...

sounds like the bov valve requires attention. increase the setting so it takes a little bit more pressure for it to open.

Well, if I check the connections tommorow and try replacing the filter, I guess it would point to the BOV. I do not think there is an adjustment screw on the gfb, but I will check again. Either way, I want to go back to the stock one, the aftermarket bov is pretty much useless in everyday driving. The problem is I can not find any place that sells the stock one, and I would like to avoid going through the dealer. I am even coming up short on e-bay.

Ah, well before I buy any parts, it is going back to the dealer, still under warrenty for another 6000 miles/September 05 so I might as well use it. Filters didnt do anything, it might be the BOV, but I bet its some loose vacuum line. Its weird because it only does it if the car is in motion and coming to a stop, if I am already stopped and rev it, it will idle normally with no dip/stall.

If the BOV chscks out OK check the plugs. and yeah, KingPin as a literal box of them last time I checked. Unless they threw them out already.
http://www.kingpinperformance.com Just look up the phone number on thier site and call them direct. Ask for a used stock BOV.

Well, I abused my warrenty and had it brought into the dealer to check for all and any leaks. Car checked out fine, no leaks, no lines disconnected or anything. They told me it was either the Catback ( ) or the BOV, the only 2 'performance' things on my car.

It has to be the bov, the problem is I have an older version of the GFB Hybrid, and it does not have the adjustment screw/hex key hole on the top for easy spring adjustment. So you have to open the damn thing up, re-lube it and add a washer. I e-mailed GFB directly, and they told me the same thing.

I ended up getting a stock bov from someone on here, but I dont think he shipped it out yet . So I am just waiting a while for it to come in, and I will post back and tell the outcome.

I would just open the GFB up now and go to work on it, but If I lose a part from opening it up while still under the hood, or something gets messed up, I wont even be able to drive the car and I cant miss anymore work. When I get the stocker back on, I will open it up and do what needs to be done then throw it on ebay or something.

My old Ford Escort started doing that at one point. After sitting at idle for ~30 seconds it would start sputtering, then die. It was a vacuum (intake manifold) leak. The shop tightened up--I think--the airflow sensor and all was good again.

Finally got the part in, ended up installing it outside in the dark in 20 degree weather because I am retarted. Ended up throwing in a new airfilter also since mine never got changed as stated before.

Took her for a drive, problem completley gone and car feels super strong again. Iam gonna pop open the GFB, clean it up, add a washer and throw it on e-bay.

hmmm, my car just started doing this recently (rpm's dip when coming to a stop), I assumed it had to do with the ol/cl fueling change on the recently revised CObb maps. maybe I'll pull my plugs this weekend (stock BPV). . .
