My 95 Nissan Altima runs sluggish and wont accelerate when I press the gas pedal. What's wrong?

Question

I have replaced fuel filter, air filter, plugs and wires,

Answer 1

Get the timing adjusted

Answer 2

Check the throttle position sensor (TPS) to make sure it is working. if there is ever any engine knocking, use better gas - knock sensor will retard ignition timing to stop the knock and it can kill performance. Several other sensors could also be involved, the mass airflow sensor, oxygen sensors, etc. You could have a vaccuum leak on the intake system somewhere, your ignition timing could be off, your timing belt could be stretched or slipped. When you replaced the plugs that would have told you if it was running lean or rich if you look at the condition of the plugs.

Answer 3

1st check the distributor..oil leaking on the camshaft position sensor common. 2nd intake manifold gasket failed causing unmetered air to enter before mass air sensor resulting in a misfire condition.. 3rd check the mass air flow sensor ...

Answer 4

Press harder.
