Anyone know what size they are. I think I put too small in and now my car idles like hell (air leak obv) and spit some smoke out at me too.
It's the cups that are in the head holes that the injectors seat into. thanks.

 

I did this same thing. Just went to the hardware store and matched the sizes. Car ran horrible and had a terrible miss anytime I gave it gas

 

yeah it blows ***** lol...anyone know the size for sure? guess i'll try to match if noone does.

 

I wish I could help you bro.... but I had to say, I love your sig

 

GMpartsdirect sells a kit for like $30 that comes with the buckets w/ the rings, injector o-rings, the clips and all sorts of misc. parts. I will have to find the part # I have it laying around here somewhere

 

Ok thanks. I just put the old ones back in and lubed them up for the time being so that it's driveable.
So annoying whenever I get into boost I get this hissing noise.

 

Did you ruin one or why are you replacing them?

 

I was getting a hissing whenever my car went under boost so thought maybe an o-ring was bad and causing a leak.
Last night coming home from work I pegged 20+lbs of boost before i realized and got off it.
It's sitting in the driveway till monday and hopefully can get a tow truck to get it haha.
Drives like dog ****, exhaust is so quiet now, smelly kinda.
Believe the cat is the culprit.

 

Well because I am a nice guy for a little money I will send you the ones that came stock from my car. They will be the injector buck with the o-ring on them Just pm me for info

 

I would say you are correct in believing it is the cat. Hopefully you get it solved soon
