Ok so the last few weeks I've been having a nagging knock sensor issue. Swapped the harness to my z1 harness from my previous motor and no more code. Car still felt sluggish though. Decided to attribute my sluggish performance to a fuel pump that I'll be replacing next week.
So few days ago I decided to reset the ecu and the car felt alive again so no reason to worry about it any further.
Guess I was wrong
Did a scan of my car today after I felt a slight stutter upon acceleration and this is what I found
This is quite disturbing lol .OK so my transmission has always driven fine. A bit sluggish but I perceived it to be the knock sensor itself or the fuel pump.
For this many codes to pop up at once I find it hard to believe my most of my transmission components decided to **** the bed all at once.
I did read a thread about a P1762 that could have been caused by a faulty fuel pump and coincidentally the post said something about the fuel gauge showing a quarter of a tank. Mines had a quarter of a tank as well.
So I'm hoping there's another culprit at hand that caused this issue. Fluid is fine, color is good and so. Is the smell I don't really beat on the car so that's not an issue as well. Car is driving fine as well, I'm assuming because the codes are pending??
I decided to clear the codes and see how it drives home tonight.
Also it was pouring outside while driving, like flood level rain lol.
Any ideas? Hate to believe the trans is going out when I just replaced the engine last year...... I'll continue to update this post as more information comes to mind.

Update.
Took the drive home, it's about a 20 min drive. No issues or trans related codes. Still having that nagging knock sensor code lol. Will update tomorrow after taking a drive again.
I think you have an electrical problem, clean up all those grounds, and pay particular attention to any damaged wires. The knock sensor problem though, did you replace the sub-harness or the sensor itself? The main point of failure is usually the sub harness but if you already replaced it then you probably need to tear off the entire intake and replace the sensor itself.
This is day 2 driving it after I cleared the codes and they haven't reappeared. I'll be changing the knock sensor in the morning and update the post. This sensor makes my car feel like a 4 cylinder Honda lol
Just updating this.
My sensor was fine, after doing some poking around I found out my Z1 knock sensor harness was sitting on my exhaust and melted it. I cut out the burnt section and respliced things and all is well so far.

That's interesting! Neat find. Goes to show nothing better than going down there and looking around !
And the code is back lol. Decided to show itself during a 2 gear pull. Typical flutter stumble. Blah. Ordering a new harness today. If that doesn't rectify things then an oem sensor will be bought. Good times lol.
