Hi everyone, today I replaced my broken oxygen sensor (can hear it rattling when shaken) as well as my spark plugs. Prior to this the car ran just fine without any of the current symptoms. After I changed out the oxygen sensor and spark plugs and saw the symptoms, I tried to set the idle by warming it up and disconnecting the TPS then set idle.
Currently the symptoms includes:
1. Idle is moving between 850-1100. Most of the time it is at 8500, but once in a while it revs up to ~ 1100.
2. Between the above range it is also breaking up and I can feel/see the vibration of the engine. Basically sounds like it hiccuping.
I replaced the oxygen sensor with a skinny Nissan sensor. As for the spark plugs, I'm currently using those V-power BKR7E gapped at 0.28. The last time I checked they TPS voltage it was at 0.45 at idle, I didn't think to check the voltage at WOT.
Thank you in advance for any input, I want to sort this out soon before school starts again.
