rebuit ficm still getting po267 dtc, have hot shot and rev-x in it. edge cts says ficm good. ficm was bad when sent off for rebuild. have had truck for 2 months now. have done flush with restore and +. need to install new thermostat, 1 in is bad 148/ 184 deltas. Did oil change to 5w 40 syn and mc filter. Will be installing new fuel filters when blue spring arrives. Did clean rgr valve, need to do again, get code every now and then. So with po267 should i just replace injector or have shop check out?
