Chevrolet dropped a 2.4-liter in-line four-cylinder engine under the hood as standard equipment in its 1999 Malibu base model. The base model had an available option for a 3.1-liter V-6 engine, which was standard on the Malibu LS and LS Gold Edition. No matter which engine or trim package, the Malibu came with a four-speed automatic transmission. The data link connector in your Malibu accommodates an OBD II scanner to read trouble codes.
The DCL in your 1999 Malibu is an open connector on the driver side under the dashboard between the driver door and the steering column.
