09 nytro idle HELP!!

[Keith1962]

Here's the pressure sensor. https://www.partzilla.com/product/y...MIt9T0m6zd4AIVh4qzCh17agyuEAQYBCABEgLRe_D_BwE
Sections 7-14 and 7-15 in the service manual refer to this.

Hmm that was changed with the throttle bodies what are the chances they both were bad? I hooked my power commander up and added and subtracted fuel with the idle only going lower. It runs great otherwise just idle.

 

[Keith1962]

Very unlikely they both are bad, so the wiring harness is the more plausible problem. Do you have a service manual?

 

[Keith1962]

Any luck with this?

timing jump?

1st
You have two pressure sensors above your throttle body’s
1st one get reading from cylinder 1
2nd gets reading from all three cylinders
Make sure they’re properly plugged in n zip tided in place
There specific placement is important

2nd
Your controller has a variety of inputs to calibrate the unit and more then likely is setup to run on tps readings . Mine was an acted like you said your sled runs. I opted for a pressure based input instead this way I can’t set my afr to auto tune and let it do it’s thing. My tables are base on 5 pd of boost so I made a table based on 11
-5,-4,-3,-2,-1 0+1+2+3+4+5 set the afr to boost pressure

I have 430cc injectors 26 % bigger then stock so my idle input numbers where corralled around this number till auto tune kicked in n made it’s own tables. Finally it idled hot or cold
My fuel economy is dictated by my thumb

A few questions
Stock injectors?
Plugs n gap ?
How much boost?
Octane you run ?
Fuel pump external ?

Sorry didn’t get notifications. Still this problem persists. I have ordered a wiring harness, not really sure what else it could be? Most everything else has been changed.

Timing is spot on!

Your pcv isn’t configured properly

Na that’s not it, it was present when sled was bone stock too. Added the turbo etc no change

Your pcv isn’t configured properly

The sled still runs the stock injectors controlled by the stock ecu. I have the secondary injectors that I control with the pcv

 

[Davidonmars]

Here is a data log. At wot it runs perfect.

Check your TPS

Check your TPS

It’s good checked in diagnostics goes from 16-96 steady when throttle applied

So I would like to update the forum on what the issue was. Turns out it was the reluctor ring. I guess it slipped and threw the timing off. I’m not sure how this even happens. If your vipers or nytros will not idle this is definitely something you want to look at. Remove the clutch and pull the stub shaft out and you should see it right away.
