Partial 12v Power cut out when driving
Has anyone encountered this?
Driving, seems to be around 3k rpm and before half throttle or blipping throttle check engine like will flash on with battery light and PRNDL light will go out. RPM will drop off and then power will come back on and will rev for a second. Almost like someone puts the ignition into ACC.
Radio, blower, headlights, dash lights all unaffected during this.
So far I have cleaned all battery connections and all grounds and checked ohm's of all the cables, main 80amp fuses.
Checked power at PCM while causing issue and voltage stays at PCM. (PCM does not lose power or ground)
