The Nissan Path

I just bought a 1997 pathfinder SE 4x4 187000 miles.
It reaplaced a 1996 accord rust bucket/ deathtrap

Anyways. I have noticed that on startup it will sometimes idle a little rough, but then clear up after driving for a few minutes. It also runs rough on occasion when backing up.

The SES light is one, took it to Auto Zone and they said its pulling a gas cap code and misfire code the guy said most comon for a simple tune up....(for the life of me I cant remember the code numbers though, and i literally just left the damn place 20 minutes ago)

Does it sound like the short periods of rough idle are because it does need a tune up, or possibly because of something else...Other than the problem describled the car runs great.

anything?

id like to get whatever it is fixed before it becomes really serious.

wow, really 105 views and not a single person can offer an idea......

thanks guys! ill find another board to go to.

It could be a tune-up issue. Would help if you remembered the codes. These engines also had some issues with the fuel injectors getting dirty and sticking and a TSB addresses the issue; basically says to perform a professional fuel injection system cleaning before replacing any injectors. Stick with genuine Nissan or NGK parts when replacing any ignition system components.
