[03lincoln]

2003 lincoln town car executive. Started with the seperation of thermostat housing and crossover. The coolant leaked into driver side coil/ plug wells and caused misfire. Parked the car for a few months to save up for new intake manifold (Dorman). replaced all spark plugs with motorcraft and put in new manifold. Crunk up the car and gas poured out of the top of cyl.8 fuel injecter because fuel rail wasnt properly bolted. <- Fixed) crunk up and had misfire from the once submerged coils <- replaced) SLIGHT HESITATION/STUTTER under low rpm. usually around 50. replaced all other coils today but noticed there was some moisture in well 5. cleaned out placed coil back in and still the stutter, also changed the fuel filter. NO SES LIGHT

NO SES LIGHT

You need an OBD readout regardless of the no SES light..
