Ok so the other day my dummy light came on and when i checked it it said the car was running to lean and that it was from a vac leak. I found the leak in the hosing for the pcv so i replaced all of it and pulled the pcv to check it. When i put it back in the car would die right after i start it unless someone would block off the pcv hole. So today i bought a new one as soon as i started it it started to die bt then kicked back up the rpms. Let it run about 7 mins or so and took off and now its back to just dying again. Anyone know how to fix this?? Just so you know its a single port pcv because i have a cold air intake so it only attaches to my intake mani and it screws into my valve cover

Try disconnecting the battery for 15 minutes to clear the computers memory so it can relearn the new idle trim. It may have learned the idle with a giant vacuum leak and now that you fixed it, it's wanting to idle too low.
