MPFI making me go Crazy!

Hi,

As you guys know I finished my MPFI swap.
Well, the car start right up perfectly and idles good.
But the car still wont rev past 3000 RPM!
With the car turned off but the ignition on I get these codes:

6: Coolant Temp
10: Intake Air Temp
13: Atmospheric Pressure

Today I just put a new Intake Air Temp sensor in cause my old one the plastic was broke off. I thought that by doing that it would make code 10 go away and possibly 13. But it didnt.

I also tried shielded wires from the C1 ECU to dizzy.
That didnt work either.

I double checked my wiring and checked to make sure nothing was loose and all the wires are soldered correctly in the right places.

I really dont know what to do. I gotta get this car running.
Its almost impossible to not be able to rev past 3000 while driving.

So if any of you guys could help me it out it would be greatly appreciated.
Thanks

Did you also shield C2, and did you try other wires than those rcas?
I dont know if rcas are shieled or anything, but the shielded wires i got worked.

try swaping the wires for the intake temp and the coolant. there are three or four plugs on the engine that are exactly the same.

Ok ill try.
But where exactly are the plugs?
And all I changed was the intake manifold and ECU.
What would be the number one cause for the 3000 RPM rev limit?
Im about ready to take the car to a professional, lol.
Thanks
