My Hyundai Sonata GLS, with 2.5 Liter 6 cyl.

You cannot, First thing you need to do is get the codes using a diagnostic scanner that is able to access the airbag module. Your basic code reader will not do this. The code will tell you what airbag has an issue. If your a smoker in the car most likley the ASH destroyed the clockspring under the steeing wheel.

Change spark plugs 2001 4 cyl hyundai sonata

You change One spark plug, and One wire at a time. Do you know where your timing belt is? If not, its on either the right or left side of the engine. There is a covor to the timing belt. You take the First plug that is closest to that belt. Then you work your way to the next closest all the way to the last one. Remember, you have to do ONE at a time.
