little problem w/ swap Options

Ok.. fire it up.. when cold it idles fine.. about 1100-1200... as it warms up.. the idle goes up.. and then **** starts to get bouncy and it's just not running right.

I did a check for vac. leaks.. Pretty sure there is none.. But I checked the timing.. bridged E1 and TE1.. used the light.. It's right on 10BTDC... so that's fine... No check engine light when engine is on.. but when I turned it off and I left the jumper wire in to check for codes.. I got code 12

"No G1, G2 or NE signal is input to the ECU for 2 sec. or more after STA turns on."

This might be why the RPM reading on my Apexi AVC-R is only telling me 200rpm when the tach is reading above 1500rpm? I think I noticed that sometimes when I rev it, I see the Apexi reading shoot up to the actual RPM value but then it quickly returns to crap.

Also once it warms up it doesn't like to rev up past 2K unless I smack the throttle good.. otherwise it hits 2K and then chokes.

Any idea's???



Also I should note that this is a 2nd gen motor, fully rebuilt.. using a GT28 turbo.. FMIC, stock AFM... Um.. Distributor is the original.. I did the wiring up on it myself.. I am using the Alltrac fuel pump and the resistor pack for the injectors and the fuel pump relay and resistor pack.. all that normal crap is in there..

I might be jumping the gun here but I'm almost certain I fixed it up.

First thing was, I put a clamp on the hose feeding the IACV... that lowered my idle... so I assumed that the IACV was stuck open... more on this later.

Next thing I did was adjust the TPS... with the IACV hose completely clamped shut I had to use 7% throttle to keep the engine going and reach 2K RPM... no stutter out this time.

So I adjusted the TPS.. loosened the clamp on the IACV hose.. so the engine would idle but lower... turned engine on.. came up to like 1500rpm.. then I slowly put throttle on like before.. hit 2K.. went past 2K.. no problem. The Apexi AVC-R was telling me I was putting down 2% throttle... How truely accurate that is, doesn't matter.. I was barely touching the throttle like before when I was having issues.. now I no longer have said issues!

So then I ripped the IACV off.. tried to move the valve inside and it was stuck!!

Thanks for everyones help/idea's with the issue.. I will report later or tomorrow to confirm if everything is good or not.

So I had to rip the whole valve apart and cleaned it out with carb cleaner.. moves smooth and freely now. I am going to seal it back up and this should fix me problems
