Here recently when I start my car I've been noticing that at idle it runs rough. What I mean is that behind the car you can feel there isn't a constant stream of exhaust the way there should be. You can also hear this in the engine and see the engine have sort of a pulse. The only thing that I notice from just eye balling it is that the EGR tubing looks like it isn't flush to the EGR valve. Any thoughts?

Check your PCV valve. Carefully take it off and shake it. Look inside for gunk. If ok put back on and try more troubleshooting.

No lights coming on. The car starts fine and does run. It also runs smooth once you drive a bit but the roughness just concerned me. I have this posted over on gaownersclub as well and I've had two votes for PCV, one for MAP tubing, one for FPR, one for Cat, and one for generally manifold leaks. I have some diagnostics to do today lol
