Ok as much as I hate to admit I need help. I am working on a 1994 F150 4.9 The engine idles well but when I give it throttle she bogged down and a little black smoke comes out the exhaust. Ok here where is gets interesting. I installed a new TP sensor no help, next a PCM no help, Then AIRB solenoid no help, Then AIT sensor No help, ECT sensor no help, Checked timing 10BTDC “OK” New plugs, no help I have a Dura spark EEC ignition wanted to change the stator assembly but could not find one ended up replacing the entire distributor, Cap, rotor, and wires, no help.
I tried to pull DTC codes but I could not with KOEO, I did get codes from KOER. But they are probably false codes. I do not know if the PCM has gone into HLOS mode. So out of frustration I pulled the head and had a valve job done, put it back together, The engine still Boggs down. Can some one help?
