Check fuel pressure; replace the fuel filter if you haven't already done that.
RPMs are usually spark plugs and wires:
pull the spark plug wires off the spark plugs, mark where they go.
Cylinder 1 is the one toward you, looking at the engine from the front, to the left side. 1234 is the left side, 5678 is the right.
look in the holes for coolant. if the intake leaks, it ends up here and causes this problem. You Have to both fix the leak, AND buy new wires.
pull the plugs. do this with the engine cold. be careful, and don't break any plugs. If you do, get all the pieces out before you pull the plug out.
clean and gap them to 0.54" (~1.4mm)
reinstall the plugs and space the wires away from the engine with something non-conductive and run it, and see how it runs.
