NO idle and doesnt goe higher than 4k
Okey here is the deal. I had a lot of problems getting my car STARTING. The engine is a Jspec and doesnt make it easier. My first problem was that the primary rear injector didnt fire but i fixed that. Now does both fire!
I change plugs and got the baby runnin but it wont idle and nither go higher than 4000 rpm. When i press the throttle hard it stalls but again i can go up to 4000 before it stalls..
Summary:
-It idles only for 4sec before stall
-stalls if i push the throttle to the floor
-stalls over 4000 rpm
-Both rotors got spark and fuel
What can cause these problems?

Sounds like either leaking or stuck secondary injectors... Or another problem, but I'd definitely concentrate on the secondary injectors!
They kick in at 3800rpm, or straight away at WOT, both of which are causing you problems!

MY secondaries are in great shape but they dont fire! they dont get any signal from the ECU.. What tells the ECU to fire the secondaryies? Can it be the AFM?

the primarys work fine it is something with the signal to the secondarys.. but my wiring is okey from the ecu to the injectors.. maybe there are some damaged sensors but witch sensors controlls the fireing of the secondary injectors?

i dont think thats necessary since i had it all running once and i KNOW the secondaries dont fire.. but i dont know why :S
While i was testing right now i tried to run it as near to idle as possible.. got it running on 1500 but on 1400 it reved up to 1800 and died.. as my motocross does when it doest have any more fuel.. what is this?

your secondaries won't fire unless you're out on the road. They should never fire at idle.
So if you arent getting fuel, then look at your primary fuel injectors.
But my suggestion still stands...

no the secondary injectors only fire under load.. Look in the FSM
So if you are just dead-reving it, the secondaries have NOTHING to do with it..
like I said, look at your primaries and do a compression check.
The compression check may be fine, but you'll feel a lot better doing it now and having it be bad, then doing it later after wasting time and $$...

Compression Check .
Check AFM per FSM (get to do this myself soon, yay)
Set TPS with 2 light method
And finally, check to make sure it will rev over 4000 when its actually on the road, not just sitting in neutral.

manifold vacuum is at 0, and it is at wot
secondaries will fire.
