I have a 2003 Bonneville that's throwing a P0300, P0301, and P0201 code. I have replaced the coil pack, plugs and wires and the injector in #1 cylinder. Before replacing any parts I had the P0301 and P0201 code. With new plugs, wires and injector I got the P0301 and P0300 code yesterday. Today I replaced the coil pack and I'm getting the P0201 and P0301 code. I know it's a Bonneville, but it has an L36 in it. Thanks for any help.
