Misfire codes can be caused by a range of failures. Spark Plugs, Coils, Injectors, Manifold gaskets could all be suspect. When the check engine light is on and the car has stored codes, your first reaction is to replace the parts mentioned in the stored codes. But that can often lead to money being wasted replacing parts that you don’e need. Your best bet is to have the codes interpreted on the spot by a qualified technician. That way they can inspect the related systems to make judgement about what parts are working, and what parts need to be replaced. You can have this done at your convenience by contacting Your Mechanic. They can send a technician to your home or office to check out your Alero and let you know just what it is going to take to fix it.

My cars speedometer just now started wiggling and going back and forth and sometimes to 0 mph.
I would recommend changing the speedometer (https://www.yourmechanic.com/services/speedometer-is-not-working-inspection). I recommend this because the speedometer on older vehicles from the 90s have a manual gear that turns the it. It seems as if the gear has broken and only contacts the needle...
