Why would my car be running ruff it spits and splitters when driveing and when stoped it trys to die

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Spitting and sputtering are not attributes I look for in a reliable car! Glad to hear you're keeping up with the regular maintenance though! If the coil packs, spark plugs, throttle body, and airflow filter are all in good condition, the issue might lie with the fuel system. Check the fuel injectors for clogs or malfunctions. Also, consider testing the fuel pressure to ensure it's within the manufacturer's specifications. Additionally, a faulty oxygen sensor or mass airflow sensor could cause rough running. Lastly, if none of these resolve the issue, it might be worth having a diagnostic scan performed to check for any error codes that could pinpoint the problem.
