The first place to start for the "chug" problem is to replace the fuel filter and run injector cleaner through the fuel system. Replacing the fuel filter is pretty cheap and can be done when you get your oil changed. If you are a hands-on type of person, there are plenty of videos on youtube about how to do that. You should be running injector cleaner through the fuel system about as often as you have your oil changed, unless you routinely use a gasoline containing detergents such as Chevron's or Holiday's does. Injector cleaner can be purchased at almost any gas station, auto parts store or even Walmart. This goes into the gas tank when you fill up, and will clean the entire fuel system. If it isn't the fuel filter/injectors you have a problem most likely with your fuel pump. This is a more costly fix and should be done be a mechanic.

If you are overheating or not getting heat in your car you will want to have the radiator flushed and the thermostat replaced to begin with. The cost for that is pretty minimal and can be done fairly easily if you like to fix things yourself. If that doesn't help or only helps a little, you have a heater core problem. This may require something as simple as back-flushing the heater core or something as nasty as replacing the heater core itself. If you smell antifreeze when you turn on your heater, the heater core needs to be replaced. This repair is labor intensive and is very costly. Above all DON'T LET YOUR CAR OVERHEAT!!! This can warp the engine block. A car with a warped engine block needs to be taken to the junk yard or have the entire engine replaced.

But don't panic. It sounds like just general maintenance stuff and the cheaper options to me. Good luck! :-)

Fuel pressure, fuel contamination, throttle position sensor, mass airflow sensor - these are all things that could cause the car to bog out at any given speed. There's certainly plenty more but these are what I'd start with.

Regarding your coolant question: asked and answered in your other post. But from the description in this post, your coolant system is working fine.

Sounds like a clogged fuel filter, try changing that and if it still chuggs, try a fuel additive like an injector cleaner. It is normal to not have heat at start up, as the engine needs to warm up before the coolant is hot enough to heat the air being blown through the heatercore.

I agree with Teddy on the "take it to a shop" your question on "chugging" is too vague.
As far as the Radiator question....easy.....you start the car...wait till warms up, if one radiator hose is still cold and one is piping hot....NO your radiator is not circulating

you need to find the fuel pressure release around the fuel rail press the little tab when the car dies. If there is no fuel coming out from that point, your fuel pump is going.

If vehicle was left outside or in an unheated garage, there is a strong possibility that condensation has contaminated your fuel. Easiest way to check is to remove fuel filter and pour contents into a glass jar. If you see two different layers of liquid in the jar, the bottom part is water. Replace with new filter and drop the tank. Remove sending unit. pour contents into a large container and clean out inside with clean dry rags. Remember, fuel is dangerous to work with and fumes travel pretty far on the ground. So, no open flames electrical stuff, cigarettes etc for a good perimeter around work area. Generally, you can re-use top 3/4 of fuel you removed by syphon. Don't use remainder in your vehicle. Part can be used for lawnmower etc as long as you only take the part above the water line.

SOURCE: 1995 Nissan sentra cutting out when given gas

If it is bad gas you would be able to smell it usually. When gas goes bad it turns to like varnish and the smell ( believe me- once you have smelled it) you will never forget what it smells like. If the engine light is on, check the trouble codes. On a 1995 Nissan Sentra it was the first year of OBD 2 systems so it should have a hookup for the scan tool but if you don't have a scan tool you can still retrieve the codes from the ECU or the check engine light.
Under the dash behind the center console is the ECU. You will need to get to it(Don't disconnect it from it's wiring harness ) Just be able to access it and I believe on the side of the ECU isa Diagnostic Mode Selector which you will move to the left and turn ignition switch to on position(not start) and watch how the check engine light flashes. Sometimes it will flash fast and sometimes slow. Then it will repeat. Example a long beep then 4 quick beeps would be a code 14. Write down what yours is and get back with me. Good luck.

Sounds like you are getting too miuch fuel and not enough air. Try replacing your spark plugs and wires, then cleaning your throttle body. Replace the air filter too if its been awhile. This will probably fix the problem.

Have your fuel filter changed, your fuel filter may be at the end of it's life time and is dirty. The fuel filter should be replaced every 15,000 miles or once a year to ensure that the fuel system is running at 100%. Try that first and if there is an Auto Zone around your area, have the car scanned for the DTC codes. Auto Zone scan free of charge and can give you the recommended steps to addressing the issue that is causing your engine problem. Good luck and keep me posted, be glad to help you get your car running 100% again soon.
