What would cause shuddering and loss of power from a dead stop with 93 Skylark 6cyl?

Not running on all cylinders Could be: Bad plugs Bad Wires Burned Valve Bad Piston Plugged catalytic converter Do compression test Possibly none of the above. No power under a load could be the torque converter. TCC solenoid wire is on a connector that is at the rear of the engine in the bell housing easily seen once the air filter is removed. With a voltmeter check the voltage on the white wire should be 12vdc. It is similar to trying to pull off from a light in 3rd gear with a standard tranny. It could be stuck in lock up mode (overdrive). Take it to a transmission man.
