Sparkplugs have heat ranges, you need to stick with ac delco for those.

make sure you have ngk or ac delco iridium plugs installed. Also common problem on the 2.2L ecotec is the cat plugging. Easy check is to remove the front o2 sensor (very easy 22mm wrench) and start the car and rev it. If it revs freely now and does not bog the cat is plugged. They are covered fed. emissions warranty 8yr 80k, all gm dealers stock the cats for the 2.2 ecotec.

SOURCE: replacing spark plugs on a 2004 chevy malibu

2.2L Engine

  1. Observe the following service precautions:

    Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  2. Turn the ignition OFF .
  3. Disconnect the Electronic Ignition (EI) module harness connector.
  4. Remove the spark plugs using a 5 / 8 inch spark plug socket.

To install:

WARNING Do not coat spark plug threads with anti-seize compound. If anti-seize compound is used and spark plugs are over-torqued, damage to the cylinder head threads may result.
  1. Inspect the gap on the new spark plugs, re-gap the plugs as required. The spark plug gap specification is 42 inch. (1.0 mm).
  2. Install the spark plugs and tighten to 15 ft. lbs. (20 Nm).
  3. Apply dielectric compound to the spark plug boots and make sure no corrosion is present.
  4. Install the ignition coil housing to cam cover and attachment bolts.
  5. Tighten the ignition coil housing bolts to 89 inch. lbs. (10 Nm).
  6. Connect the EI module harness connector. Push in until a click is heard and pull back to confirm a positive engagement.

SOURCE: I want to change the spark plugs on my 2004 chevy

You can change the plugs if you would like, however those plugs last 100-150k miles. I would clean the throttle body and replace air filter. I have repaired this complaint many times on these vehicles. The throttle body becomes blocked by debris and lack of maintenance. Br very careful when cleaning. Make sure key is off and push hard on plate in throttle body clean by hand. This part is very hard to press has extreme amount of pressure behind it and you could badly hurt your fingers if becomes trapped under plate. You may want to have someone else there just in case you should slip or not be able to press and clean it at the same time.

My 2004 chevy malibu classic 4 cyl wont start its


There are four things required for an engine to run: air, fuel, compression and properly timed spark. If you have fuel and timed spark, the only two variables are air and compression. Air is not the likely problem, and compression should be good unless you blew a head gasket or the rings in all four cylinders. How did you determine that you have fuel and spark? Those are the two most likely problem areas.

GM swears the plugs will last 100k miles, yet I have had to replace them as early as 30k miles.(That was on my wife's 05 Pontiac montana.) A word of advice: Don't get the fancy aftermarket double or triple platinum plugs. I had to replace those again 5k miles later. Went back to ac delco platinums and they're still working after 50k more miles.

2004 TB EXT. Lately its been running rough. When I start it, it has a quick vibration-noise then stops. When I turn it off, it makes a weird stumble(very fast) then dies. Sounds as if the exhaust is...


1st things first, clean that throttle body with carb cleaner with the battery disconnected.


Check your motor mounts and transmission mounts for the vibration at start up and when your foot is on the brake. I just went through this with my TB. The mounts may look ok visually, but they may be going flat. Changing the gear oil won't solve anything you have described, however, it's time to change, then change it.

Did you recently change your spark plugs to a brand other than AC Delco 41-103's? I've seen platinum plugs make our TB's run rough also the worst is Bosch. Stick with the iridium Delco's, will have a smoother running vehicle. Hope something in here helps.

Routine Maintenance


I would change transmission fluid and differential fluids. check to see if it has a fuel filter also I know they stopped putting an inline filter somewhere around your year model and just has one in tank that doesnt have to be changed. you can also change air filter and inside cabin air filter located behind glove box . The spark plugs are platinum good for 100,000 then tune up needs to be done. plugs and wires, use only ac delco platinum plugs and ac delco wires. a little more expensive but way better to me than the others. they have coil packs so there is no distributor cap or button to replace.
