Spark plugs and wires are where I'd start; check and see of something is living in the intake or exhaust.
Change the plugs with the engine totally cold, after sitting all night, and put penetrating oil on them before you start.
You might also look down the holes, and see if there is water in there.
If the engine rattles while it's having issues at 3k, it could have a bad fuel pump; you can check the pressure at the schrader valve on the fuel rail.
