5.3 tunning going horribly wrong

[Angeldelgado]

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 shakes and pops alot, not an issue but it may not be a good thing.


Hp 1.hpl
base tune basic.hpt

I had the wideband connected to hp tuners but for some reason the math parameters were not showing up.

I just need some tips on how i can get this damn thing going please!!!!!

CODES:
p0336

What's your fuel pressure?

Did you smoke test for vacuum leaks or exhaust leaks?

How is the PCV system plumbed, your other thread showing you where venting to atmosphere but also running a MAF sensor??

[Angeldelgado]

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 the tb.
However after you mentioned the PCV system I was a little curious on how it’s actually Plummed up.

Ihave a ls1 intake but it’s truck everything else.

I replimbedthe rear left side pcv to the front intake on the right and plugged up the front right valve cover nipple
And yes I’m running a truck MAF, should I remove it or??

But it does shake a lot not sure if that’s normal for a ls9 cam
Thanks in advance

Sounds like you are sucking air out of the crankcase there is no vent for it to be replaced. You must resolve the P0336.

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

Don't pull the motor to check the reluctor. Remove the starter, remove the crank sensor and get a bore scope--one for your phone is good---and look in the hole for the sensor. You can see the sensor and tell which one it is. 24 reluctor is in two discs, 58 is one disc. Im sure there internet pictures.
