1995 Nissan Truck 6 cyl Four Wheel Drive Manual

My truck started missing badly and does not accelerate well, but it idles normal. I already replaced the fuel filter, distributor cap and rotor, plugs and wires. This did not fix the problem. No codes showed up on the computer at all. What could possibly be the problem?

Is there engine light on? Check fuel pressure and inspect spark at plugs to ensure they have healthy blue sparks.

There is no engine light on, and the spark plugs, and plug wires have just been replaced, along with the distributor cap and rotor, and the fuel filter. The fuel pressure was checked and was at 40 lbs.

Just because plugs are new doesn't mean they are getting good spark. Also check cylinder compression

Thanks will check, have also been told that a few different sensors could be bad such as the oxygen sensor, airflow sensor, throtle position sensor, or the pressure sensor. Does this sound like it could be the problem to you?

Could be but faulty or failing sensors will almost always set off the engine light. Without it setting the light, it would be a guessing game as for which sensor to replace
