I have a 1995 Nissan Altima with 150000+ miles on it. When the car has reached normal operating temp and you press on the gas the engine stumbles and dies most of the time other times it will act like you are taking your foot off of the gas peddle and pressinging again when really you are maintining constant pressure (jerking motion), it also dies when you come to a stop. When the engine is cold it seems to run OK, until it warms up. I have replaced the spark plugs, wires, cap and rotor, fuel filter, air filter, the coil tested within specs, I have also replaced the fuel pump, and checked for oil in the distributor (found none and replaced the O-ring to be safe). The check engine light does not come on when this happens. Where do I go next?
