No KOER codes
My 86 Bronco II 4wd automatic will not display KOER codes. Nothing not even engine ID. I get KOEO and memory and timing check- thats it. I'm trying to fix a stuttering/ rich running after warmup problem and KOER codes may help. O2 sensor is new (Bosch) new hp fuel pump, regulator, map sensor, EGR solenoid, battery ground cable, fuel filter, dist cap, tfi module, rotor, plugs. Throttle position sensor checks good. Less than 700 mi on remanufactured engine. Fuel pressure was low now is OK. No leakdown after shut down. This problem is driving me nuts!
