Owner Letter

December 13, 1993

Dear Chevrolet Nova Owner:

This notice is sent to inform you that Chevrolet Motor Division has made changes to an emission recall campaign that includes your vehicle.

During October 1992, General Motors notified owners of certain 1988 Chevrolet Nova vehicles with 1.6L engines, that their vehicle may exceed high altitude carbon monoxide (CO) Federal Emission Standards. This condition only applies to vehicles registered in Colorado, Nevada, New Mexico and Utah. Owners were advised to take their vehicle to their Chevrolet dealer so that the condition could be repaired.

It has been brought to our attention that some vehicles which were previously repaired for this condition may be experiencing driveability concerns (hesitation during engine warm-up and, for manual transmission vehicles only, rough engine idle). We have determined the cause of these conditions, and Chevrolet dealers can make the necessary corrections.

If you have not yet returned your vehicle to correct the original condition, please make an appointment as soon as possible with your Chevrolet dealer. We will correct the condition free of charge with a new repair procedure that will prevent the driveability condition from occurring.

Please also make an appointment with your Chevrolet dealer if you have had the original repair performed and are experiencing the driveability concerns mentioned above. The necessary corrections for these driveability conditions will also be made free of charge.

If you have already had the original repair performed and are not experiencing the driveability problems, there is no need for you to return to your dealership for any corrections.

Should you have any questions regarding this program, please feel free to call us. Our toll free number is 1-800-222-1020, and one of our Customer Assistance Specialists will be happy to answer any questions you may have.

We are very glad to have you as a customer and hope you will choose Chevrolet again when you make your next vehicle purchase.
