misfires are caused by lean conditions , fuel pressure, plugs and ignition failures and leaking intake gaskets check your fuel pressure first. the egr valve stuck open will do also . should be easy to figure out.

It could also be one of your ignition coils. You should have 3 coils (2 cylinders per coil). If you can get the old ones off you might be able to have them tested at one of your local auto parts stores. Usually a new coil for a GM vehicle runs around the $25 to $30 range.
