Today my engine light came on and towards the end of my commute (45 miles) the car started bucking upon acceleration (twice it happened). Is it a timing belt issue, faulty spark plug?

There are dozens of issues that can cause your driveability problem and MIL to come on. A proper diagnosis by a reputable shop will prove benficial.
If the timing belt were to fail, the engine would shut off. If a spark plug were to foul, your car would still run, but not smoothly.
If your engine is listed correctly as a 2.4L then you have a chain , not belt. Some problems occur with the chain guides/tensioner affecting the 'cam timing' code will most likely read 'out of phase' that problem will lead to poor running conditions -sluggishness-. Regular oil changes with the correct oil(5W20) are best prevention for that.
