On 250-500 mile trips, I am experiencing considerable soot in my tailpipe on my 96 5.0 V-8. A few weeks later, it clears up. This time during a long 500 mile trip, I got a check engine light that came on and then went off after a couple of days. The truck has about 96K on it. Has original plugs and wires and does not use any oil.
Some have suggested changing upstream O2 sensors. Any other thoughts? Thanks Mike
