Looking up the error codes I see that:
P0306 is "Misfire Detected (Cylinder 6)"
P0278 is "The P0278 is a trouble code which can be defined as Cylinder 6 Contribution/Balance Fault. This code would represent an unusual amount of voltage being detected in the vehicle's fuel injector circuit."

This just started happening yesterday and I immediately pulled over to make sure nothing obvious was broken.
I noticed this the first time when I started to accelerate on highway it started shaking and I immediately pulled over to check if anything was amiss that I could visually see.
Now Idling the car shakes a bit but goes away for the most part when slowly accelerating.
Driving slowly the car shakes when I try to hard accelerate
I drove home(slowly) and plugged in a simple error code reader to see what was going on.

Anyone experience this before?

Also any suggestions on good mechanics around Charleston SC area?
