I have a 5.3 ls out of a 2002 Tahoe. It has the Truck Norris nsr cam and a Holley midrise dual plan intake with a Holley dp750cfm. I'm running a MSD 6014. I put in a new cam sensor in because the 6014 said it was faulty. The engine is running like it is out of time. It is popping in the carb and out of the exhaust, it also smokes a little bit and the spark plugs are black. the spark plugs are brand new. I would really appreciate any help
