I have a 94 Pathfinder 3.0 V6. Recently, it began having problems with excelleration. At startup, the truck is okay. After driving for a while, truck begins to sputter and acts as if it will shut off. Sometimes, when I let off the gas pedal and then press it again, it goes okay. But, sometimes this doesn't even help. I have had the truck serviced. You know, tune-up, oil change, plugs, distributor, wires, etc. The check engine light has yet to come on. Have no idea what to check for. Maybe Catalytic Converter? Injectors? How would one go about cleaning the injectors. Any help would be appreciated.
An easy way to check to see if any of your injectors are NOT working is to 1. Start the engine, 2. unplug the injectors one-by-one.
If an injector is working correctly, then you will notice a loss in power.
I also suggest trying to get a hold of a "Nissan Consort" and have the codes checked. Autozone have ways of checking the codes. Remember the codes only point out an area where a problem exists NOT what part isn't working.
Hold the phone.. If you look under the moderators post, you will find a helpful little guide on reading and deciphering the check engine codes. Kinda sounds like a clogged converter or a bad coil/coil wire. Did this start after a certain event? Plug wire change/tank of gas/accident/New Car Fever? I get the last one alot... Aaron

My pickup does this. Usually on very humid days. It starts fine and idles fine. After a couple of minutes, it begins to run really bad when trying to accelerate, even from a stop. Letting off the gas drops back to a perfect idle. The problem always goes away after about 10 minutes of driving.
Usually the main cause of this is plugs, wires, cap, rotor, or all of the above. Akelron - when was the last time you had a tune up? GnSShockley - Arron is right, I'd go back and check the wires from the tune-up if that was recently. If all is good - then it could possibly be a fuel pump, injectors, or fuel filter. You could install a temp booster pump and see if that fixes it, run some additive to clean the injectors (or rajnaz's idea), new fuel filter is an ez must - they should be change regularly anyway HTH
