92 explorer sport emitting soot from tailpipe
i installed new plugs and wires for a simple missing problem.a few days
later the check engine light came on.also,there was soot coming from
tailpipe-fuel economy went wild. I changed mafs;checked tps;and other
related sensors.i had it hook-up to code finder at parts store and was
told my computer was not putting out any codes or not working correctly.
can anyone tell me what is going on.
