Just because you replaced all of the vacuum lines does not mean that you cannot or do not have any vacuum leaks. Vacuum can leak from any vacuum powered accessory such as the EGR diaphragm, a myriad of other vacuum controls and from your intake itself.
Not 100% sure if any of yours are, but some heater/A/C controls in the passenger compartments are also vacuum powered and it can leak there too.
