Nissan Repair: 2000 3.3l nissan, vacuum leaks, knock sensor

Question
my truck is misfiring and throwing a code p0300 misfire and a knock sensor code. have changed wires, plugs, cap rotor. and mass. still misfires. all started when i went through some deep water. I also check for vacuum leaks. checked injector ohms. all seem good. how likely is it a distributor?

Answer
Hi Justin -

It very well could be the disributor. Have you tried to remove it and clean it out? There is a module in there that cannot get wet. Perhaps you can dry the inside of the distributor out. Aside from that you have checked all that I would have. Unless water got into your gasoline.

Hope this helps -
aloha
