Slight throttle dies
 

Ok fellas, so here's the issue. And before you say it, yes I have researched and tried diagnosing.
This happens when:
Partial throttle is applied
In any gear, At rpm:
Afr - - -(dashes) out lean
Dies at idle
Face plants driving

If I baby touch the throttle its fine and drivable..ish except up hill not enough air flow/power:
- 1.6v to ~3.9+v

At ~4.5v partial throttle that's when dash out lean Afr hits
During idling it WILL cause engine to die.
While driving it will cause power loss and nose dive
When I press just past "dead zone" throttle, 4.5v half to full throttle, afr jumps back up to normal operation

So I'd say
0 to 10% throttle input gives normal afr

~15 to 25% is the "dead zone"

~30 to 100% throttle input gives normal afr
If that makes any more since.

I have checked for any possible vacuum leaks, all resolved.
Timing
Swapped around afm, tps, barometric pressure sensor. No change.
Put my rtek 2.1 to factory settings. No change.
Swapped around injectors. No change.

If any other info is need, please ask.
This issue makes it hell to drive slow in residential, or go from a stop without spinning wheels.

Thanks, Brendan

the exact same thing happened to me and fixed it today. one of the small pipes to my intercool was broken.
