NISSAN SENTRA GXE 2000
I RESENTLY REPLACE SPARK PLUGS AND COIL PACK
IT WAS WORKING FINE AND THEN MISSFIRE SHOW UP
MY GAS PEDAL WAS GETTING STUCK HARD TO PRESS IN THE UPPER LEVEL OTHERWISE WORKING THEN THE CAR STUMBLE ,CRANCKING AND STAFF LIKE THAT
TRY TO PUT THE OLD COILS DOESNT MAKE DIFFRENTS NEXT MORNING THE CAR WON'T START
SCAN WITH OBD SCANNER SHOWS P1320 And P0300

p0300 - random/multiple misfire
p1320 - ignition signal

you have a cable driven throttle body, are you sure you didnt break your cable? maybe its getting stuck, i would replace it since your gas pedal is sticking or hard to press. hopefully its not the tb locking up.

you may have the cam/crank sensor issue, have you changed them recently? your p1320 isnt common, but it says ignition signal. so this could be a bad coilpack, or bad cam/crank sensor. otherwise you may need to check some wiring for this one, it would be somewhere between the ingition cylinder and the ecu, and the ecu to each coilpack. follow the fsm for correct voltages, there could be break or lose wire somewhere. considering you just replaced the sparks and coils, its possible one of the coilpacks are defective, which would give you both ses codes.

how does the car not start? does it turn over? do you hear the fuel priming? does it crank and stumble/shake/misfire? did it start and run after you replaced the coils and spark?
