Ok everybody I got the oil changed with Nissan ester. The sound at a hard pull is still there. I wish I could explain the sound better. Anyways. Today I decided to make pulls form 3k to 4k as I got close to 4k the sound showed up as usual. I maintained 4500 rpm and the sound leaves. Pull from 4500 to 5000 and the sound comes back. I maintain 5000 the sound leAves. Same when pulling to 6000. Noise while making it to 6000 but leaves as soon I match the throttle to maintain 6000. Could it be injectors? Almost sounds like when a spark plug is tested when you can see the spark jump. Just a random fast sparatic sound.
