wiring and vaccumm problem

[limecorrado]

ok, i have a couple questions.I have looked in the search.

heres my problem my car runs poorly.when the mafs (ka24e mafs) is hooked up this way the engine will idle good but won't rev over 2500 rpm

Black-blackblack/white - black/white green/yellow - white green/black - not connected

when i have it wired with the other way with the green/yellow wire off the engine will rev through out the rev range but will not idle and die.

do i need to change the MAFS or is there another way to wire it correctly

also, when i run and ecu diagnostic it give me code 34 and code 12 which say i have a cas problem and a MAFS problem.what could be wrong with the cas the wiring has'nt been toughed and it seems to be working ok.

also what do you do with the vaccumm hose directly above the turbo the connects to a steel line and wraps around the engine?

and lastly my ca has a hicas power steering pump can i just plug the back part of the pump using a hydraulic fitting and use the front part?

Sorry i had so many question i'm just getting so close to getting my car mobile and i only have a few small hang ups.

Thanks in advance

I am having the same exact problem with my MAFS wiring. I'm going to the junkyard tomarrow to pick up a couple of MAFS to make sure the ones I have arent bad. When I wired mine up, I wired the green/yellow and green/black wires to the white wire. But still, running waaaaaaayyyy rich, no idle and dying.

Thanks,Mike
