Ahhhh okay okay okay thank you.
Ill revert back to just the PE tweak.

Hello there i need some help tuning my vehicle.
After finally getting the car to start correctly i can now tune it :)
however no matter what i do to the VE table the car goes rich 10.5 then goes...

I’ve tried to fix it. Replaced the sensor. Ima try a new one again before I pull the motor and check the relictor wheel.
This motor is upsetting me :(

The fuel pressure is 70 when priming and once it’s done it hovers around 58 ish give or take 1psi.

I don’t have a method of vacuum testing with a smoke gun but I did find a leak near the front by...

I have 5.3L Gen III with an LS9 cam
The build was completed but the tune is the issue, It does not want to idle correctly. At first the car ran fine I was even able to drive it at one point.
Motor...

I think I may have found the problem, well I’m going to confirm it tomorrow, is there any way to make sure that I did not mix two similar looking wires??? When I accidentally cut the tac module...

Yes they are. Well the pedal is 01 Tahoe now but I can always use the other one which was from the 03 avalanche, the tb I replaced 3 times now but I think I have the original somewhere

Yeah I did that when I modified the harness don’t really trust butt connectors, however I did do it for the injectors to make sure that the injectors worked. That being said butt connectors are being...

I did , when I was modifying the stock harness. That’s probably were I messed up, I had accidentally cut the throttle body connector cable, well the ground. I can find the diagram again. Any ideas on...

well i switched off both the pedal and the throttle body. and p2135 does not seem to go away now. I do not have control of it. both items were taken off a runing truck. perhaps a short in the...

maybe maye i sure hope so. Lucky for me i work at a junkyard so i can get "Free" parts thats were all these faulty sensors come from.
But yeah ill get a different peddal assembly and a different...

i added system battery voltage, maybe wrong channel ill add all the battery chanels see which one shows data.
And the throttle code is not new sometimes the code will go away if i turn the car off...

Ive already replaced the Throttle body once im not sure why this keeps on happeneing. At times it wont even react to me pressing the pedal


perhaps its the Peddal assembly, I had to modify it to...

0x10: P0120 - Throttle/Pedal Position Sensor A Circuit (Pending, Current)

when i hit the peddal it just keeps shaking as if i was rappidly pressing on the pedal.
That is...

Alright I’ll add it here in a sec put up a log as well

The set up I have is .
Filter. Pump. filter/regulator. Filter. Y fitting. Both fuel rails

Yeah I saw other people’s build and they only have one side plugged up I assumed it wouldn’t be an issue ... I’ll plug it up as soon as I can . Also it’s the same line it’s just split into a Y...

This is my current set up sorry about the wiring mess i dont really plan on fixing it until i know the motor is good.

i dont remember what code it was but the fuel pump was constantly on never stopped so im assuming it may have gotten the signal mixed up when i shut the car off and turned it back on immediatly, btw...

Both tests were done minutes apart, to make sure i didn't forget to connect something. Motor sounds different

alright so im hoping that replacing the intake gaskets fixed some of my intake leaks concerns and replacing that vacuum hose that leads to the th350 to a much thicker one so that it doesn't split...
