I recommend having a mechanic come and look at the vehicle to check for vacuum leaks or coil problems. You may need to replace the coil pack and ignition module. These older engines may not register misfires as well as newer engines can, due to the better programs and sensors of today’s vehicles. You may have a carbon build up on the valves that need to be cleaned along with the fuel injectors. Have a certified technician, like one from YourMechanic, diagnose your car’s misfire firsthand and help you fix it accordingly.
