Hey guys any help would be appreciated. I recently deleted my diverter valve on my 305. Before this my car ran like a dream. I took it off but now when I start the car up it runs really rough. It kind or revs up and down for about 5 seconds then it straightens itself out and runs normal. I noticed when its having the start up problem that it blows out white smoke from the tailpipes for a couple seconds then will stop when it runs right. Also I pulled the plugs and there covered with carbon deposits which I believe means its running rich and the plugs are only about 2 weeks old. Any help would be much appreciated in letting me know whats wrong. Thanks
