Customer Question

2000 frontier 3.3 v6 misfiring.
Mechanic replaced distributor and plugs. He also tried plug wires and MAF. Also replaced injector for cylinder that is misfiring.
Originally started with a knock sensor code. Mechanic relocated. No codes now. Replacing distributor solved the tach rpm bounce.

Thanks for the question! Were all the parts factory or aftermarket? On these cars aftermarket parts won't always fix the problem and sometimes even create new ones.

The distributor was not remanufactured but don't know if it was factory. The mechanic gets his parts came from Napa.
one more symptom: One spark plug had been coated in black and looked sooty. The black went up over the ceramic.

If they're not from the dealer, they won't work properly. I've seen it dozens of times with aftermarket parts especially ignition parts. The first thing you'll need to do is put all factory parts in (plugs,dist cap, dist rotor, and plug wires.
