I drive a 2007 Ford Mustang 4.0 and noticed a rough idle. By rough I mean shaky and loud vibration.
Sounds a bit like a power surge.
My rpms stay at a steady 750 and I just replaced the entire clutch assembly.
Im thinking maybe spark plugs are causing it?
Any thoughts?

Check for wet plugs, if not that, then check transmission and brakes

Could be anything related to air, fuel or spark.
An easy check would be to inspect the spark plugs, check the condition of the spark plug but also look at the ceramic coating to see if you can see any cracks. Cracks usually have a burn mark on them so you should be able to spot them quite easily. The spark could be jumping out the sides not giving full spark to the cylinder.
Then trace it up, test the HT leads or coil pack.
Check the throttle bodies aren't getting stuck in a weird position at idle too.

Could possibly be a misfire. my first suggestion would be to check the spark plugs and see if they're looking good. Most common cause for a missfire is Coil Leads or Spark Plugs.
