I recently bought an altima 2j plenum and i got it all bolted on and all the vacum lines ran into the plenum. But the car will not start it just cranks and cranks. I had to Y off some vacum lines into the same port since the stock b15 manifold has 5 ports while the altima plenum has 3. Please need help getting this car to start with the new plenum. Ill post pics once 8 get home from work.
