Sure, go ahead. New engines aren't all that expensive.

If your knock sensor is giving a true reading, you are probably using a fuel that does not meet the octane requirement of your engine. Could you possibly have filled up with 85% ethanol? If you continue running the engine while it is knocking, you will damage the pistons and experience run-on or dieseling. If your knock sensor is giving a false reading, you won't experience engine damage but you will get lousy gas mileage because the computer will try to retard your timing and change the fuel/air mix. Get it fixed. It is cheap.
