So my 2002 maxima is having a misfire problem not a specific cylinder but it’s random I replaced the connectors to the coil pack replaced the coil packs with new oem ones and replaced the plugs I don’t know what’s wrong I think it could be a fuel injector but I wanted to come on here and get a better guess or opinion on what it could be.

 

I really need help with this it’s my first car and I’m 16 and did all the work on it myself

 

Curious. How do you know you have a misfire problem? Did you get any codes?

 

Sounds like your maxima is experiencing the P0300 random misfire, check for vacuum and intake manifold gasket leaks.

 

I did get the random misfire code
