I was 2 hours into a 3 hour drive today and out of the blue my car started to run really rough. I pulled over and checked all the connections on the COP's and ensured they were seated on the plugs. I took off and it was still running bad. I pulled back over and reloaded my tune and that didn't help either. Drove the rest of the way home feeling like I was in a helicopter. It feels like it is not firing on a cylinder. Any ideas???
