After I grounded out my vtcs I notice my car has a shimmy like it's misfiring or something. What is that and how do I fix it.

 

... a little more specific would help us out.

the word "shimmy" a side to side movement or a back and forth movement?
listen to your exhaust at idle , does it sound like its skipping or have a hessitation ? does it just "look" like its moving but sounds okay? have you checked your spark plugs? what about testing your coils? have you done any maintenence or had any done lately? give us a full explenation and we can try to help you out more.

maybe post a video or sound clip so we can see/hear your issue.
-thanks

 

Unground your VTCs and see if it goes away.

Crappy idle is common after grounding the vtc's.

 

Don't you have a switch wired up to unground them for lower rpms?

 

Yes sir.
