car still shakes when at light, after having changed all the mounts on 1992 Toyota Camry

I changed all the motor mounts on my car and it still shakes.
Also changed the distrib. cap, spark plugs, wires, erg valve. Just confused as to what the problem is?

Is it a misfire or an engine vibration? If engine, put a floor jack under the oil pan and raise engine slightly to get the weight off the mounts, and see if the vibration goes away.
