I have a 02 Xterra 4WD Manual transmission. I recently replaced the plugs, wires and distributor. Since replacing those parts I am actually getting much worse mileage and if you stand too close behind the car while its in neutral, it will make your eyes water its running so rich. Its also very sluggish on acceleration and has basically no power.. im wondering if I have the ignition timing off from when I replaced the distributor, but this is my first time owning a Nissan vehicle, so im not too familiar with the commonly flawed parts.

Thanks in advance!

Were the spark plugs gapped to OEM specs or did you buy pre-gapped plugs?

I put in pregapped NGK plugs, I replaced the distributor with a brand new one a few weeks ago, the old one was coming apart inside at the bearing and causing some serious misfires. But now I'm getting around 12 mpg.

Personally, I never trust pregapped plugs. It doesnt take much to check them. I suggest to pull the plugs and ensure all of them are within specs.
