Shaking after coil pack change

Hey guys. I just got finished changing my plugs and coil packs in my 08 Vantage. I started the car and now it's shaking and not running very well. I haven't driven it, just idled. The plugs have the right gap and they are the right ones. Please help me.

If it has more than a 1/4 tank of fuel, it should bring on the CEL emissions warning message. Any reason why you changed the on plug ignition coils?

Sounds like one or more plugs or coils isn't seated properly, or there's a loose connection so one isn't firing. Are you getting any CELs?

I torqued the plugs and they all seem like they seated just fine.

Depending on fuel level it may not have a light on or code stored. You could have washed down the cylinder with fuel. You can wait for it to evaporate or remove that plug again and add a small amount of engine oil 1oz or less. Do you have a scan tool or code reader?

Since the battery was probably disconnected, it could be as simple as having to re-learn misfire correction. There are several threads here on the subject also check out aston1936 who has an excellent write up on the subject.

I sure hope that's all it is.
