Hey guys!
Here's a quick update on what's happening!
Car runs fine, just a few minor issues to take care of.
(1) Car stalls for about a second at an idling stand still after I brake for a red light, or stop sign, etc. When I press the accelerator, sometimes (not all the time) the car will stall for one second as I press the accelerator and then suddenly jerk forward as if it just woke up -- like "OH (#&*$( time to go! and the car runs forward" causing a jerking like motion.
It definitely shouldn't be low on fluid because I brought it to Nissan Dealership to make sure the fluid was correct at operating temp. They found out it had 3 extra quarts of transmission oil, and drained excess.
Prior to that, I drove the car around the block for a total of a few miles then drove it to Nissan Dealership which is 2.3 miles away, so maybe about 5 - 6 miles total driven very casually and extremely slowly (yes even on the public street on the way there) 20 - 30 mph average or less with the extra 3 quarts of oil.
(2) P2A03 code thrown intermittently (aka) O2 Sensor Circuit Range/Performance Bank 2 Sensor 1.
- In my logs, I checked both short term fuel trims and normally, both bank 1 and 2 should be the same wave lengths. However, Bank 2 is more wavy than bank 1, which means there is a slight leak somewhere around the Passenger-Side upstream o2 sensor or even could be from the downstream o2 sensor that could have thrown the code. Not sure. I am going to have to check that out too. Maybe it wasn't tightened down all the way or something when the passenger side cat was installed.
(3) Extreme pulsation / vibration when on highway / cruising at ~60MPH. The vibration is so bad that it shakes the rear view mirror so intensely that I can't even see what is behind me clearly because it makes it all blurry. Almost as if I had an insane sound system that vibrates every mirror on my car with an extremely low bass sound -- except I have no such thing in my car and I was also not playing any music / radio / etc.
I read that this issue is due to me not having a wheel alignment and/or tire balance correctly done on my vehicle since the transfer of parts.
So I will try to get a wheel alignment and tire balance completed as well today if possible and if there's time.
(4) Slight engine oil leak occurring because when I came back home after the Nissan Shuttle drove me home, I saw in my garage fresh engine oil leaks. I checked to see what oil it was because the transmission fluid is vastly different color than the amsoil engine oil (Ruby Red [vs] Thick apple juice colors). I will see if Nissan can find the source of the engine oil leak as well while they're at it.
Other than that, the car internally runs beautifully according to all the logs.
Once those issues above are fixed, my car will be ready to go!
And now that I learned patience throughout the last 2 months, I am definitely not in a rush and am willing to wait as long as possible to make sure the vehicle is 100% healthy before I can continue tuning it! Yay!
PS: Someone said my car is making too much torque which is why the transmission is stalling, and because of that, my stock 7AT is not able to handle the mods I have in the car and therefore I will need a new Tranny -- I hope this is not the case though. He said based on his own experience, he had the same stalling issue I did or similar at least, and it ended up being his tranny not able to handle the amount of TQ his Z was pushing out. which was... 450 WHP / 390 TQ
So idk.
We'll see folks.
Stay tuned!!!
EDIT:
I did a bit of research.
The culprit for issue #1 /could/ possibly be dirty throttle bodies.
Here is 4 things that I experienced which match to my vehicle.
