I have a 2001chevy s10 4.3 4wd auto, it runs good until it's warmed up, then once it's ... the gas pedal causes bouncing on the tachometer and loss of power. ... when driving at a steady speed if I try to accelerate the engine tries to die

Your picture of the light didn't seem to come through. Several things will cause restricted power.... a dragging emergency break, a plugged fuel filter, plugged air filter, plugged exhaust pipe and finally check all the fluid levels in the motor as some cars have a limp mode if a level is too low, especially on the oil side.... also make sure the gas cap is tight... a lot of viechle will act up if the vapor return line doesn't have the proper pressure in the gas tank. Next would be wires and plugs, distributer cap and distributer button... spark plugs can run fine at low rpm but foul at higher rpm.

According to my owners manual for my 5 speed 1999 S10 it's 18.5 gallons (70.0L) standard tank.

What codes did you get & look up?

There may be more specific solutions along shortly, but my older car had similar problems until I changed the ignition module. The "spark box" as it was nicknamed. My car was a mustang, but it only seemed to act up on hot days, and if I just pulled over and allowed the car to cool for a bit it would go again just fine. I'm not familiar with Nissan trucks specifically, but it's another place to consider. Good luck!

well you leaking gas either from your fuel pump tank float assembly inside the tankand gasket is bad that seals the fuel in or possibly a bad fuel neck aka filler tube also check your fuel lines and make sure all clamps are tight

Go to your local shucks or auto zone and they can check any codes behind your check engine light and it's free. It sounds like one of two things a O2 sensor or your mass airflow sensor but they will tell you for sure

Sounds like it has a hard miss. Any engine codes? more info is needed there are a lot of things that could be wrong.

check for water in the tank...When adding fuel it gets stirred up and enters the system. There is space beneath the fuel pickup that allows contamination to remain there. Eventually it will get to a point that it becomes critical or rusts tank from the inside. Check inside filter, pour contents into a glass jar. If you find any water drop tank and clean.

my fan switch on my 1999 chev. s-10 want work on high speed, what's wrong
