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?

 

I just checked and I forgot to plug up one of the coil packs . I plugged it in and it still shaking.

 

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

 

No CELs.

 

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?

 

I do not have a scan tool

 

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.
