Having problem with running rich on 2.9 liter. Once warm the engine idles ruff. Under 2/3thirds to full throttle engine runs properly. Once you back off of throttle to cruise it starts blowing black smoke and missing.
I think I have replaced every sensor on the vehicle,the O2 sensor, map sensor, EGR valve and sensor, swapped computers, checked the voltage on the TPS sensor.I am at a loss of where to go next. Any help would be appreciated.
