Did you check the codes while concern was present? The inner connectors are bad about coming partially apart after warming up but it will set codes when doing the buzz test. High to low circuit codes on which ever bank its related to. Wait till it starts doing it then do a buzz test & listen to the inj's buzz. All should be loud unless theres a circuit concern.
