My 93 Civic just miserably failed its smog test. The HC was slightly high and the NO was more than double the allowable limit. The car has just over 100K miles.
Last week, I had a dead battery and since then, I’ve only driven the car 10 or 15 miles, tops. I’ve read that when the battery dies and the computer resets, that can cause such failures, but this post seems to indicate that this is only true of cars made after 1996: http://community.cartalk.com/discussion/2213598/failed-ca-smog-test-due-to-coputer-reset
Could the computer reset be the problem with my 93 too? Or am I up a creek?
Any ideas or advice would be much appreciated!
