So I'm having a similar issue and didn't want to start another thread:
Car started and ran fine about a week ago, but always had a prob;em once it got warm in that it would hesitate for a split second when you blip the throttle or try to accelerate, and would sometimes die out if you let off the throttle quickly after applying throttle...well I just went to move it and it won't stay running. 1993 Sentra XE, turns over fine, seems like it wants to start, and 20% of the time does turn over and run for a few seconds. If I let it run it'll go for MAYBE 5 seconds and chug out. If I even think about touching the throttle it chugs out (dies).
Just swapped the fuel filter with a new one, has a few fresh gallons of gas in it too with a bottle of drygas. Didn't help whatsoever but the fuel system was pressurized, and I have the taste in my mouth to prove it haha.
Within 20k it has a fresh dis cap and rotor, plugs, and wires.
Any ideas? I'm still searching around but figured I'd post here just in case.
