lately my 33 gtr is down on power and splutters everytime i put my foot more than 1/4 throttle. it hunts up and down on idle and even stalls. So i hooked up nissan datascan and it came up with error code 12 everytime i started the car, which is bad AFM connection it says. i re-soldered the AFM'S but still doing the same thing. Anyway im about to buy a set of rb26 AFM's and hope it fixes it. However I just want to confirm the voltage an r33 GTR afm runs as nissan datascan says mine are .95 volts on idle. Also my o2 sensors seem to be buggeed as the reading just keeps goin up and down, but i dont think it would cause such eratic behaviour would it? just stupid fuel consumption.
