I had the same issue on my car for over a year. Im not to car savvy either, but im learning
I have the same car you do. What i did to fix the issue was replace the
-Fuel filter (like 15$)
-spark plugs (2$ bucks a pop, you prob need 6)
-transmission fluid and filter (25$ or so total)
-PVC valve (5$)
-Oil change (20$)
-Air filter (8$)
I also changed my Radiator, serpentine belt, Master Brake Cylinder and booster, fuses but those are also unrelated
Would also make sure all you fluid levels are good
The below link is my forum thread explaining the issues i was having my car.
Im also going to be replacing my Crankshaft Position Sensor.
But these are normal tune up things that the car needs every 12,000-20,000miles. I neglected mine for over 70,000 and she was hating me, now she purrrrrrrrrrrssss and starts ohh so much better.
