115 johnson moor spits and sputters when idle and stalls when shifted into gear

SOURCE: 1992 SE maxima jerking, sputtering, stalling

I had a similar problem and resolved it by replacing the mass airflow sensor. Ive got 235k+ miles on my 1992 Maxima SE.
Still runs good but having problems with the alarm system.

SOURCE: Van Sputters And Loses All Power When I Accelerate

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).

SOURCE: RPMs fluctuate, sometimes stalls at stops, wierd shifting

check throttlr sensor

SOURCE: No power, no acceleration, spits & sputters

Clean out clogged fuel injectors
