I dont have the money to buy an O2 sensor this week. Can I drive my 93 civic without one for the week or is it bad for the motor or will it even run at all?[/align]

 

Can't say exactly on your Civic, but on my '95 Contour it ran pretty ragged and barely idled. Check prices at a couple of auto parts stores, they aren't that expensive. The dealer charges the big bucks.

When the O2 sensor goes out the computer sets the mixture very rich as the default setting, thus the ragged running.

 

Thats what I was thinking. Thanks for the help.
