I had a 2000 gmc which jerked bad and I thought was transmission problem. I found it was bad map sensor. If you have check engine light find out what the codes indicate. These days electrical controls mechanical much of the time.

jerking can be from many things
1: brakes locked up. or bad.
2: engine jerks
3: transmission jerks.

sluggish, same,
find a shop any auto repair shop to tell you which of the 3 it is.
then post for help.

keep in mind, not one person here can drive your car. and see that.

Sounds like you almost snapped a.U-JOINT. have a.mechanic remove the drive shaft and repair

similar problems: After 20min cool down jeep was bucking/lurching that I traced to bad o2 sensor in exhaust manifold (which you've replaced is seems). The second problem of bucking/lurching, backfiring under certain driving conditions I traced to the battery sliding into the computer wiring harness, disrupting sensor input / output signals. I cured this problem by placing a 1" spacer on rear battery clamp, pushing the battery forward. Been years and no return of problem.

It's the transmission sensor. I've had mine replaced three times now. You can fix it (see this thread: http://www.suzuki-forums.com/suzuki-forenza-reno-forum/35284-transmission-range-sensor-all-you-need.html) and please report it to Suzuki at 1-800-934-0934

HAVE SOMEONE WITH A FLASH LIGHT LOOK UNDER THE HOOD WHILE SOMEONE ELSE INSIDE THE CAR HAS 1 FOOT ON BRAKE AND 1 FOOT ON GAS KEEP GOOSING THE GAS WHILE IN DRIVE THEN SWTCH TO REVERSE GEAR AND SEE IF MOTOR MOVRES ALOT IF SO BAD MOTOR MOUNTS

the main dealer unless you have a auto factor somewhere

Step 1: Check/test your TPS (throttle position sensor).. it may have bad spots in the potentiometer.
