I'm planning on buying a 1990 civic hatch to commute from school to work - which is about 70 miles apart. The car I'm looking at is in good shape, a little rust, with 130k miles. Everything ran really smooth and quiet. The only problem: the check engine light is on? Is this a typical problem for this model, like could it be just a bad sensor? Please let me know. I'm taking it to a garage today to have it checked out.
