SR20 swap, MAFS problems!

[boycelaforest707]

Hey everyone! Just swapped my sr20, here is the problem:
It starts and idles, not a very smooth idle... anyway you cannot rev it up or it dies.

What I have done:
Checked ECU, code 12 MAFS
Checked wiring from MAF sensor to ECU
Tried a SOHC MAF

Other stuff:
I have 12v on the black/white stripe wire @ maf, the black ground wire is good all the way back to the ECU, but:
White wire reads 12 volts with key on, ignition off, if I ground the black wire to chassis (in addition to ecu) it drops to around 1 volt.

What should it read? Is my ECU bad?

Thanks guys!

any air leaks?

Nope, triple checked intercooler piping...

check your air filter adapter. It may be blocking the sensor.

I have just the MAF, no airfilter or airfilter adapter.

check ur maf wires and to the ecu and if its all good i has to b the timing is bad im pretty sure its ur timing

maf is toast! or could be a funky wiring problem.....those SUCK

Tried another MAF, wiring was tested back to ecu, try again.

Maf wires tested back to ecu. I will pull valve cover and inspect the CAS/timing tomorrow, thanks.
