Guys, I have got this Used P28 ECU (was previously repaired by some tech dont' know for what reason) anyways, this ECU runs fine with my stock D16A(d16Z6) with no codes throwing on dash but when jumped the 2 service wires it throws Code 14 and code 22, why is that?
car runs fine, vtec engages properly and Idles at perfect 700ish no issues

IACV/FITV/Vtec solenoid recently Cleaned

Possibly a bad ECU?? anyone?
thank you






Code 14 Idle air control valve or bad ECM
Code 22 V-TEC pressure solenoid
