Easy104

I have a really strong feeling that it is what Mr_Reverse had suggested, but i am not sure. In the owners manual it said to change the timing belt every 105 thousand i believe and it currently has 178 thousand miles.

I believe its the VG33 but im not sure since this is my first car. I pulled the codes and all i got was P0300 which is Random/Multiple Cylinder Misfire.

Thanks everyone for the help, im in school soo I'm quite busy. But I will try to check all these things as soon as I can.

Another thing that I have found out is that it seems to run better in park or in neutral, but it runs like poo when in drive or reverse.

I have ran 2 full tanks of gas since I sea foamed it. Also I hear a strange noise while accelerating hard, it's kind of a high pitched grinding/squeal. Is that normal?

I ran sea foam through it about 2 weeks ago. And when the distributor was replaced the roter and cap were also replaced.

The fuel filter was last week. And spark plugs and wires were last year.

I have replaced fuel filter, air filter, distributor, spark plugs and wires. I recently did o2 sensors. I also ran a bottle of seafoam through the gas tank.

At first it was flashing when I stopped at a stop light and was creeping forward and then it went away. Then yesterday I pulled out of my driveway and it was a constant SES.

I need help with my 2000 pathfinder se, it has a really rough idle and check engine light is on reading random cylinder misfire. Any help would be greatly appreciated.
