Hey everyone like the title says I need help with my o2 sensor heater circut I am new to the gas world I am a 7.3 diesel man myself and my wife got a 96 f150 ext cab short bed with a 5.0 and a e4od tranny. Back to subject it gave my the po155, po141, po135 all three of thee o2 sensor heater circuts. I replaced all three of them plus changed the fuse just to make sure and it still is there it just failed emissions because of it and I need help big time thanks to everyone.
Could it be a bad ECM?
The truck feels like it has a miss but dosnt thro a code, gets bad MPG, and stinks bad on exhaust
I have also replaced plus,wires, distrubter cap and rotor plus put on a new muffler and did some cleaning
