Need help these are my issues since motor swap. Running lean at idle. Afr bouncing from 16-18's. Surging idle due to out of range Tps. Tps sensor is brand new. Just needs to be dialed in.

Checked vac lines for leaks. Found none. Replaced intake and exhaust gaskets twice. Brand new oem fuel pump. New fuel filter. Injectors were "spray tested" wired open to check flow. Emissions are still there except air control valve(which has been blocked off).

Has a SAFC II. Wiped out all the settings on it. Any help would be great.!!
