Basically....cold starts = fine.
warm starts = car revs up like normal but drops down really low and dies.
Problem solved by revving it or just touching the gas...
But does anyone else have this problem? I was told some greddy TT kits do it and others don't...
Anyone know why it does this and is there a way to fix it?
Thanks!

 

did you put your Bov after or before the maf sensor, its supposed to go after the MAF sensor

 

I have mine before the MAF like most I have seen and no problems. It is right after the intercooler.

 

when i had a maf mine was before the MAF, but i know a few people that couldnt do it, greddy told me that a BOV can do that, thats why they dont recomend the BOV with the kit

 

so is it fine after the initial warm start, or does it do it everytime you let off the gas? need to know more. return fuel system, bigger injectors, built motor?

 

BOV question n the Greddy. Do you have to have one custom fitted or is there a spot for it?

 

There is no particular spot to mount it. You need to buy a flange with the bov, and you can weld it wherever you want.

 

Thanks!

 

The most common place to mount the BOV on the greddy kits is down by the intercooler on the driver's side.

Mine is welded on the IC pipe right by the driver wheel well...How would you mount it before the MAF? It would have to be up in the engine bay, no?

 

Mine is in the same place as yours. As guess my description was not that great.

 

440 injectors (the ones that came with the kit...) and stock Fuel Return, stock internals, 5.6 lbs of boost

and it only does it on startup. If i just barely press the gas just so the revs go up as little as 100 rpms then it will stay on. But without hittin the gas pedal, it will just die. After it's on, it's fine though...

 

You car is running momentary rich on decel. When the car is cold, the engine needs a richer mixture to fire and run, which is why your idle is higher, and your car doesnt die. Once its warm, the ECU lowers the idle down, and when you let off the gas, you are momentary rich. Most people have no trouble with 440-650cc sized injectors, but each car can have its issues.

Are you certain you dont have a vaccum leak somewhere? What is your vaccum at idle?

 

vacuum on the Blitz is....im not even sure....but somewhere in the -.65's or so??? Don't quote me on that yet but i know it's up there somewhere...possibly even more
I don't think I have a vacuum leak seeing as how Street Image double checked everything after the install 2x. Eric said he was unsure why it does it but I was just trying to see if anyone else knew what was up. I still have the exhaust and a tune to do but I doubt that will solve the problem.
