My 93 has been diagnosed with having a bad knock sensor. And not passing smog Supposedly this is making it not burn all the gasoline .I have tried nearly everything else.I have two knock sensors coming anyday now .Ill let you know if it works.. Once i found one of the sensors had come unplugged at the end of a long trip. It never was the same again. Funny Calif laws ,if i move 25 miles away uphill the towns are smog exempt.
