Hesitation 900

As the weather cools off here in Southeast Texas in the morning, I am noticing some pretty bad hesitation with the Swede ('96 960)just until it warms up. If i hold the pedal steady, it's almost like it chugs, though I have been watching the tach, and it really doesn't fluctuate. If I step on the gas, it's taking a half second or so for the engine to respond. Then the RPM's jump up to normal when it finally engages...any suggestions? Note: I do have a small tear in the intake hose right where the flame trap fits into it. Maybe TPS is going south?

Fuel injector seals? Old ones are stiff, shrunken, expand when the engine warms up
