2000 Camry Missing at High Speed

Yep, the wires and plugs are original. No cap on the 2000 model just two coils with two spark plug wires each, unfortunately no way to test the coils on the 4 cyl..

Maybe its starving for fuel, see if it get worse going faster, a bad filter or fuel pump. If it was put on a scope which cilinder was misfiring would be easily seen.

I may have found the cause of the misfire, I pulled the number 1 spark plug wire to replace the plugs and the spark plug tube has about a teaspoon (guess) of oil in the bottom of it. This would certainly explain the problem.

Oil, could be it was never torqued correctly when they were last replaced and the oil shorted it, but I would worry about that plug wire also

Hello, i had the same before and everything came fine back when i changed the fuel filters. try to check them both the one on the right side of car engine and the other one near by fuel tank.

So the problem happens when the car is stopped and not at 50-60MPH?

If so it may be the problematic idle air control valve that's dirty. Needs a cleaning. This is a common reason for stalls on the camry. So check this before going to fuel filter/pump, EGR valve, vacuum leaks, etc.
