Chrysler Corp. will recall an estimated 276,000 cars to correct an emissions problem, the Environmental Protection Agency said this week.

EPA said Chrysler will correct a problem that causes the vehicles to exceed federal limits for nitrogen oxide emissions. The affected models are 1987 2.2-liter carbureted gasoline engines in Plymouth Horizons and Tourismos and Dodge Omnis and Chargers.The emission problem was found during EPA tests and Chrysler agreed to the recall, the agency said.

The automaker will install a device to help limit the ignition spark advance during some throttle positions.

Chrysler began mailing recall notices Wednesday, EPA said. The repairs will be made without charge to the owners and require about half an hour to complete, the agency said.
