The bearings on my distributor went out so I replaced it last night. I was very carefull to mark the exact location of the rotor and distributor. Now the car is running like crap, backfiring and no power. I've got a brand new cap, rotor and plug wires. They're all on the correct cylinder and firing order. I checked the wires with a spray bottle and they're not arcing at all to the block. What am I missing here?
