@chris2454l ,Chris, Engine sounds like it has a misfire issue, Bad plugs, clogged air filter, bad sensors/O2, failing knock senor, faulty injectors, dirty throttle body, EGR valve, vacuum leak, partial plugged fuel filter, failing fuel pump, coil pack failing, clogged catalytic converter, loss of compression(sticking valve, blown gasket)etc.etc.. As a first step have the car scanned for trouble codes as it may identify the exact problem. Some of the auto parts suppliers offer free code reading like Pepboys, Nappa, Advanced auto parts,etc and some of the guys are very knowledgeable and may have seen the issue often and put you on the right track. This may still not pick up the fault, as a good scanner showing live data(gives actual readings and shows sensors,etc operation) may have to be used from a good local shop. See below a couple links that may help in diagnosing. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
