Drive a 2004 Nissan Sentra SE-R SPEC V. It seems I am constantly working on this car although I do love it. Just put a "new" transmission in it but the problem had persisted before this. Sometimes it drives fine then other times it will almost refuse to go(Not limp mode). Its like it either act like it isnt getting enough gas and sorta just cut power/cough for a sec then kick back in... repeat until I press in the clutch and lets the engine fall to idle. The other symptom is that it will act like I am not actually giving it throttle input. I have replace all four ignition coils and spark plugs. It currently throws P0605: Internal Control Module Rom Malfunction Confirmed, P2135 Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation, P0122 Throttle/Pedal Position Sensor A Circuit Low Input, P0223 Throttle/Pedal Position Sensor B Circuit High Input, P1122 ETC Function/Circuit, and whatever the code for Multiple Cylinder Misfire is. Any thoughts or ideas are greatly appreciated.
