SR20 TPS values Reversed?? Idle Hunting after startup

[MrFairlady]

Car Cranks up Great (idles high for about 3 sec's like normal and then starts idle hunting.Eventually Dies.
NO Real THROTTLE Responce what-so-ever.

Checked Values on TPS and it seems its Getting .45 at about the Halfway mark instead of when closed.We've been looking at the FSM and going by what it says but trying both a Manual and Auto SR TPS.They are the same.

Closed Resistance is Def not .7
When We twist the TPS (off the car) it just seems like the TPS is reveresed of how it should be Reading.

Tried Setting the cars TPS to 45 while holding it in our hand,..car does the same thing.

We've tested COntinuity on IAC,TPS, and STill no answer whats causing my car to "Hunt" and then Die.Acts like it wants to Run Perfect.

***Items I've tried is between 3 ECU's (1 Auto 2 manual),dif plugs,tested spark - Checked Wiring etc.**

Did the ECU pull any codes?

Any luck with this?

make sure your IACV has coolant in it. I usually pull one of the lines while its running and shove it back on there when I see coolant. the idle will hunt like mad if there isn't any. Not sure if this is your problem, but that's a known symptom of that. GL.

My issue was nothing of the sort - GRANTED the Readings were reversed from what the FSM states.Bought a Brand new TPS and never used it because my issue was

The May Adaptor that allows you to Mount an Intake filter on the Z32 Maf,was 3",..but on the inside it wasn't a Perfect 3" circle - It had a Square Cut out and was covering up the wire on the maf.

I figured this out by Taking the intake cone off - and it ran great - Then Simulated a Boost leak by unplugging the FMIC pipe while running.Same Issue.
THIS Took me 2 weeks to figure out.Bored the hole out a perfect 3" inside and BOOM.Perfect!
