i have a 93 Maxima... was having the same problems with the car...i would
accelerate and my steering wheel woudl shake, my pedal would shake, very
rough accelerating, once i was doing high sppeds it was fine, unless i had
to accelerate hard to pass someone...it would happen, then it wouldn't
happen for a couple days, then it did it straight through 3 weeks, didn't
know what the problem was, thought it could be something major because the
car does have 164,000 miles on it, but never had a problem before hand....

 brought it to Nissan dealer they said either my fuel injectors need to
be cleaned or one of them have to be replaced...

so i suggest you to pick up a couple bottles of fuel injector cleaner and
throw it in your car... save you a lot of money because it cost about 170
dollars to have it done professionally.. if that doesn't work you might
need one replaced... but try this out first!

.. it even backfired/sputtered a bit.  BUT, when th
RPM's get up to 2500 or 3000, it feels fine....pulls strongly...
