    Default Rough Idle

    I know most of these topics don't get comments but here it goes...I changed the left side valve cover gasket on my 2003 A4, 3.0 liter. Now it idles rough. I had no problem before the change. There are a few things i did wrong during the procedure. I disconnected the coolant vent line and had some coolant spill behind the engine. Second, I started it without re-connecting the cam position sensor. Of course it idled rough, so I shut it off. Re-connected it and it still didn't smooth out. I ran a Vag-Com and the errors were a misfire on all the cylinders and the CPS. I cleared the codes, but it still hasn't worked. Any input would be great. Thanks guys.
