2.2 ECOTEC MISFIRES

2003 Chevrolet Cavalier

Been running great until yesterday, misfiring badly, a friends scan tool showed cyl.2 & 3 misfiring, replaced coil pack and now have only slight miss but seems to be running very rich, anyone have any ideas.

Swap #2 and #3 injectors with #1 and #4. If the injectors are bad you will get a misfire on #1 and #4 cylinders.

Have your ignition module tested, and check the spark plugs.
