How do I change the spark plugs on my 2007 Chevy Malibu? It's a Chevy Malibu LS, 4 cylinder ecotech engine. I do not want to pay $200.00 to have someone do it. My 2007 Chevy Malibu is right at 100,000 miles and is in need of a tune-up. Every place I have called wants $200.00 plus to do a tune-up on it for me. I am a single mom of three, I do not have the money for this. Any help would be greatly appreciated.

Hello,

With a spark plug socket and ratchet you can change your won plugs here is a guide to help you see what to do for the tune up.

and

Inspect the gap on the NEW spark plug(s), re-gap the plug(s) as required.
1.1 mm (0.45 in).

Install the spark plugs.
Tighten the plugs to 20 N.m (15 lb ft).

Install the ignition coil(s).

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers

You need to remove the plate at the top of the engine then you can gain access to the spark plugs. I think there is 6 bolts holding the module on.

Hello my question is about my car and how it slowly accelarates and starts to smoke inside? It Starts up but I engine really rocks and inside it shakes. Once I put it into drive or reverse the car shakes real bad. I replace the spark plugs, ingition coil pack, plug wires boots, replace the fuel pump and tried cleaning out the converter. At first when I tried it after the replacements the car went a max speed of 45 mph. It still shook but not as bad before. But before the replacements I tested it and the tool told me a misfire. So I did the replacements. Now the car starts but it shakes as bad as it did before. I took it for a test ride and the car went only 10 mph and it got smoky inside the ride so I turned around. The smell was bad too. I Need Help And thanks for your time.

The proper way to diagnose a drivability problem is to isolate the system which is faulty, then trace and test each component until the offender is found.

Hunting by removing/replacing parts never works and only costs you money that could've been spent on an experienced technician.

If you've replaced the entire ignition system already, then you're either looking at one/more bad fuel injectors or a clogged fuel filter. It is also possible that you converter is shot. A severely restricted exhaust will wreck havoc on a engine.

And if smoke is penetrating the cabin, then I suggest you take your car into a shop immediately, because that is dangerous and could kill you.

Twist and pull wires to remove them from plug. Insert spark plug socket and unscrew plug. Reverse directions to install.

Trying to change spark plugs. I did the 2 screws that hold in a coil pack with 2 spark plugs inside, but can't figure out how to open them. Are they sealed shut? I can see the tip top of the spark plug where I removed the spark plug wire connector. Only the tip opposite of the spark plug itself is exposed. Is there a way to open the coil packs without breaking them open? It looks like the plastic is sealed.

The spark plugs are in the cylinder head only thing in coil pack is wiring. Follow plug wires attached to coil to head remove boot there is plug.

Youtube may have some vids. Most say they just reach around and remove by feel, not by sight.
