Vehicle starts to buck when getting to about 65-75 on the freeway vehicle starts to buck badly and then stalls. Only had a check engine light come on once which was a p0123 tps sensor code, I have replaced the sensor and it worked for a couple of days and now is acting up again. Not sure where to check next.

Truck starts bucking for no reason when I push on throttle it will gain speed and bucking stops. this is only at a constant speed that this happens.

Does it do the bucking when you use the cruise control? If so, it's probably a bad TPS (Throttle Position Sensor)!

Bucking when O.D. at 45-55mph

I'm not certain about your vehicle, but you may be describing a problem with your automatic transmission's lock-up torque converter. Modern torque converters have a mechanism that locks up at highway speeds for a 1-1 coupling between the engine and transmission, providing better mileage. The lock-up sequence is programmed into the computer, and it is supposed to come on automatically at a certain speed and engine condition and come off when the speed is reduced or other particular conditions are met. Your problem could be that your lock-up converter is either failing to unlock due to a mechanical problem, or that it is being mis-commanded due to a bad sensor or similar problem.

My voyager kicks and bucks at times when im driving down the road what could this be ?

How could anyone guess, at that question,without the vehicle?

It could be a dozen different things

The EGR Valve could cause the bucking,also ignition problems,vacuum leaks.

On a vehicle that old,I would look for something simple.

Car jerks on freeway and engine shuts off.

It sounds like your Mass Air Flow Sensor is faulty. These sensors will normal show fault when cruising at highway speeds causing the vehicle to almost stall or stall. Replace the Mass Air Flow Sensor with a known good one and test drive the vehicle. This will most likely repair your concern.

Jeep stalls ata speed with clutch depressed.

Not being there makes this difficult to give you anything useful, however, in reading your post, It makes me think that the clutch has little to do with the problem. Likely, the engine is either not getting enough fuel or is loosing spark. When this happens, the clutch being engaged is keeping the engine turning...when depressed, it allows it to completely stop. I would first check for proper fuel flow and pressure (filter & pump), then check ignition (crank sensor & other related ignition components) The items I've specifically named are the most common ones that fail. You should verify with individual component tests as well as code tests (larger parts houses do testing free) before replacing suspect items or repairs can get very costly even when not using a repair shop.
The tests etc are too involved to write here, but are outlined in vehicle specific manuals made by haynes, chilton etc.
If you need help on specific items, I can help you with that.
good luck!

Overdrive at highway speeds is jumping in and out of gear

Sounds like your pressure silenoid is going out in the transmission. This controls when the vehicle shifts

1991 Volvo 240 bucks like a bronco and doesn't want to start.

I had the same problem w/ my 1979 242 GT.....Try looking at the fuel pump inside the gas tank (go in from the top under the mat in the trunk).....I had a broken hose that was connecting the fuel line from the in-tank fuel pump....or try cleaning or replacing the filter sock located there too & make sure the filter sock is at its proper height ! and check on the fuel pump itself....My bucking problem was more noticeable when the fuel level was low.

Bucking on Hard Acceleration

You best bet would be to look for the vacuum diagram and just take a day to make sure all of the lines to the engine and tranny are all correct. If its not it and while bucking the car feels like its going to turn off on you then it maybe a fuel delivery problem.
