I recently failed CA smog due to high hc @ 2500 rpm. Replaced plugs, wires cap and rotor. Noticed engine missing at 2500 rpm. Narrowed down problem to EGR VSV not getting power (I connected battery directly to vsv and missing stopped).
Do I just replace the ecu or could something else be bad causing the ecu not to send power to the egr vsv?
