I'm getting a weird idle but not all the time. After I come to a stop and the car idles for about 20 seconds at 850RPM then it just goes to about 550RPM and feels like it wants to die. I just installed an NX kit which included drilling and installing the nozzle right before the TB. I used silicone sealant around the nozzle fitting but I suspect I still have a vacuum leak. Does this sound like a vacuum leak or can anyone tell me how to check for vacuum leaks?

Spray some carb cleaner around there, and if your RPM's go up, thats where your leak is.
