Car hesitates and Bucks while driving we

You may need to get the system live data scanned, it will show if you have any sensors that are showing an incorrect signal or if the computer is acting erratic. Some other things you might want to check before taking it in is the condition of the tune of the engine, plugs, filters, wires etc. Could also be running lean, so a fuel pressure test and flow might also be another thing to check.
