after 15 minutes the car should be out of what is called "open loop" mode, which means it runs off the computer. once warm it is in "closed loop" mode and is running off the vehicle's sensors. the first sensor I would suspect is bad is the primary oxygen sensor on the exhaust manifold. if it is not that, it is probably the coolant temp sensor or intake air temp sensor/maf sensor. likely it is the oxygen sensor, though, causing the car to run rich and therefore slow.

A knock sensor is simply a microphone that is screwed into the engine block. It is there to listen for pinging or engine "knock" that is caused by poor fuel or extreme load. When the computer hears the knock, it retards timing, which in turn reduces the tendency for knocking, however, it will reduce power to a certain extent as well. It is possible that a faulty knock sensor can be telling the computer to ****** ignition timing too much, it is also possible that there is a mechanical problem within the engine that is mimicking the sound of knocking and retarding timing as well.
