Hi, I'm in an 05 v6, with rough idle, intermittent cylinder misfires, intermittent 02 sensor alerts, with p0193 code for fuel rail pressure sensor (high pressure) I've changed the sensor twice, new fuel filter, new fuel pump, new plugs and wires, new throttle body gasket. Can't find any vacuum leak but cannot make this code go away. Any suggestions will be greatly appreciated. Im going to purchase a new coil pack today, and maybe some contact cleaner. Please give me some ideas! Thanks in advance!!!
