SOURCE: 98 lincoln cont. idle speeds
I had the same problem. I changed the throttle position sensor (TPS). I haven't had any trouble since I replaced mine about three months ago.

Inadequate fuel pressure, change the fuel filter first, make sure the car sits for at least two hours before replacing the fuel filter because these fuel lines are under high pressure during the time of operation. The pressure usually decreases over time in the lines but wear safety glasses just the same, I would recomend depressurizing the fuel system first, buy a Haynes repair manual for detailed procedure to be safe. If problem persists go to Auto Zone and ask them to check for trouble codes these codes if present may instuct you in detail to replace the MAF sensor or give you a code that must be looked up to find the problem.

SOURCE: engine knock hard over 2500 rpm
Does the oil light come on or the knock occur during the engine warm up after a cold start?
There could be a couple of problems causing the issue. You could have an oil pressure pump or pump pressure regulator sticking. I would have a mechanical oil pressure gauge installed and verify oil pressure at idle and 2500 rpms to make sure oil pressure is in normal ranges.
You could also have excessive piston rod bearing, crankshaft bearing or cam shaft bearing wear that will cause oil pressure to drop too low to prevent the rod knock your hearing at 2500 rpm.
You said a knock and not a ticking noise,so I don't believe a lifter is the issue at 2500 rpm.
Start with the oil pressure check and go from there.
Let me know.

That's a characteristic of Nissan engines when the mass airflow sensor is not working. My 1990 300ZX was set up the same way - when the mass air sensor fails, the car won't rev above 2500RPM in order to safeguard the engine. Get some air intake/throttle body cleaner and clean the mass air sensor. Get some electrical contact cleaner and clean the electrical contacts on the harness plug that plugs into the sensor. If that doesn't cure the problem, you'll need a new sensor.
The mass air sensor is in the 3-4" diameter pipe between the airbox and the throttle body.
