You will be replacing your plugs with Platnum plugs they are pre gapped but you can also ask your auto parts store to check to make sure they are at the correct gap.
Q. Are Bosch Spark Plugs pre-gapped at the factory?
A. Most Bosch Spark Plugs are factory pre-gapped for popular vehicle applications. The gap measurements are indicated either on the box, or by the part number located on the spark plug shell. X suffix = .044" Y suffix = .060" Z suffix = .080" Gaps should never by adjusted on Platinum+4 or Platinum2. Bosch Platinum+4 and Platinum2 have factory pre-set gaps, and should never be gapped by the installer.
Bosch Platinum and Super Spark Plugs also have factory-set gaps. For most plugs, the setting is shown on the plug package. These gaps are correct for the most popular applications of these plugs. There are applications, however, for which the gap setting has to be adjusted according to the vehicle manufacturer's specifications. To avoid damage to a spark plug in the process of adjusting the gap, it is important to follow these guidelines: To widen the electrode gap, use a tool that only pulls back the ground electrode, without applying pressure to the center electrode. The tool must not be wedged between the electrodes as that may cause damage to the insulator nose. To close the electrode gap, carefully tap the plug, electrode first, on a hard surface, as shown in the illustration.

You can also go for Bosch Plat +2 or +4. They cost more but don't need to be gapped. You will always have the peace of mind knowing your plugs are working the way it supposed for up to 100K miles. I do recommend removing and checking the plugs every 7500 miles for cleaning and to prevent it from getting stuck in the engine block.
AnswerThe second guy who answered sounds like an old school fool who learned auto mechanics from his grandpa. Times change. Have you ever noticed that a pre-gapped plug comes with a protective sleeve? The reason is they ARE pre-gapped and the sleeve protects them from being closed due to dropping the package. The plugs are gapped to spec and are exactly the same. They are gapped by a machine that does a much better job than you do. Most importanly, they are gapped consistently the same wich is important for even and smooth firing. Now, if you happen to drop a plug while installing it, by all means check the gap. Otherwise, even the most skilled technician cannot gap plugs as consistently as the gap machine. Save yourself time, leave them alone unless you think for some reason they were changed. Last, on some platinum plugs you can damage the electrode with your handy gapping tool. They make gap tools for a reason, to gap plugs for your classic Chevy. :PThere should be a label on the underside of your hood that has the correct plug gap spec.
Remove the spark plug wires from your 2004 Chevy Malibu spark plugs. Remove the old spark plugs with a 5/8 deep well socket, by turning the socket to the left. Reverse the process to install the new spark plugs.

Under the hood of your Chevy Malibu there should be an engine information tag which should suggest the proper spark plug gap. If you cannot find the tag refer to your car manual that is normally located in your glove box.

There is an engine misfire, probably spark plugs issue.
Check your coil pack or the spark plugs.
