MisFire on 2005 Chevrolet Cavalier 2.2L?

[sandwds]

I took my car to autozone and they did a reading, it read multiple misfires. What is this, my car changes out very slowly. I already have changed my spark plugs and air filter.
Where is the oil filter located?

Do the plug wires now and i bet your problem will be fixed

did you change wires?

With old wires, it is possible for a spark to jump from wire to wire causing a missfire

I had a 2003, with a similar problem. First, to be easy, and always a double check is good, make sure none of the spark plugs are cracked in the slightest. If it is, replace the cracked spark plugs. This causes the same kind of arcing as the wires, but to the block itself, which can result in a useless spark being disbursed among the block instead of to the compressed gas and air in the cylinder. If none of the spark plugs are cracked, then check, and replace the wires. the wires cost about 30 bucks, and can save you some gas and add power by making all cylinders work. Definatley check the spark plugs. a small crack that is unnoticeable will in turn show up now that you have been driving on it. The crack gets charred from the arcing, and is very easily noticeable.
