Question about 1996 Chevrolet Cavalier

1 Answer

Our 1996 cavalier dies while sitting in traffic and while driving it whenever the outside temperature is humid and hot. What could be the problem?

    The cavalier does not have the check engine light on so I am not sure if Auto Zone's scan can detect the problem. We were told by some individual that it could be the crank sensor which we replaced but did not help with the problem. Any other suggestions?

Best thing to do is go to Auto Zone and have the car scanned for DTC codes. Auto Zone scan free of charge and can give you the step by step instructions to the replacement of what part has failed. I kinda thinking that it may be your MAP sensor that is causing this problem but not sure until you get the car scanned. Good luck and keep me posted, be glad to help. You may want to buy some throttle body spray cleaner too, and just follow the instruction on the can. Do Not Use Carb Cleaner, it's to corrosive for the gasket used on the throttle body.

    MAP is short for manifold absolute pressure sensor,,it senses the manifold pressure and applies the right amount of gas with the right amount of ignition timing so the car runs and performs well if this does not work properly,it throws off the whole loop cycle for the computer,,which in turn makes it run badly,,and get poor fuel economy,,it causes one to have a lack of power,,combined with a loss of fuel economy,,and also poor take offs,,and sometimes stalling,,i hope this help, The other thing to look at would be the Idle air control valve which most of the time is a easy fix by removing it and cleaning the carbon build up on it. Keep me posted.

1998 blazer excessive engine heat when a/c is on


I would look at restrictions in the radiator, both air flow and coolant flow.
Also make sure the radiator fan is running at full speed.

When my 1996 Cavalier is sitting at a traffic light, or slowly idling in traffic, the engine dies and I have to restart the car. I'm not sure exactly what it is and it happens sporadically. Also I...


That left it wide open. Does the chk engine light come on? If it is coming on, even if it is on while driving then go's off? Then it could be a sensor. Since it just dies at stop lights, could be fuel filter? How long has it been since plugs was replaced? And air filter? All of them are fairly cheap compared to how much better it runs after it is done.
However I bet it is a vacuum leak somewhere. Probably the rubber boots conecting the plastic lines to the intake. They are right against the motor around all of the heat from it. And they dry out looking like very small cracks in it. Dry rot. It don't take much for them to run differently when the rpm's drop. Be careful when you check em. They are probably brittle and break easily. And definitly change the fuel filter.

Don't know if the hot engine fan is working


The fan is known as a traffic fan because it usually goes on in heavy traffic. However, it should go on whenever it gets sufficiently hot.
If you have a temperature gauge on your car the needle shouldn't go more than 1/2 way up, or the temperature gauge if digital should not go above 220 or 230 deg. F (in GM cars) during even hot day operation.

If it goes to 260 deg. F or above, you have a problem.

If the fan does not go on with the a/c then you may have a relay or electrical wiring break that prevents it from going on when needed.

I have changed my thermastat, but my car keeps getting hot if its just idling or i am driving slow. The fan does not seem to be kicking on. is it a relay or the fan?


Hi my name is mike ! when your just idling your fan should come on after a few minutes ,if the temp is going up but no fan kick on then you have a blown fuse to the fan or a relay not working ,or a bad fan possibly .hope this helps ,let me know if you have more questions

I have a 2000 Mirage and i the morning my a/c works it cools but in the afternoon when i leve my work it blows out hot air can you help please. Les


It sounds like your air conditioning is actually not the issue here. If your a/c is working in the morning, there is no reason it shouldn't work at a different time of day. What most people don't realize is how hard an a/c system must work to cool off a car that has been sitting in the sun all day during a hot summer. Even if you leave your windows down to avoid the greenhouse effect (which can make a HUGE difference if you don't) the interior of your vehicle is still probably a dozen or more degrees hotter than the temperature outside. This is because only so much air can circulate through cracked windows, and because of the direct sunlight shining onto your vehicle's interior and upholstery. Even once the a/c system is up and cooling the air inside your car, it is still struggling against the heat stored in your car's interior, which is giving up its heat to the surrounding air as it cools off. This can take quite awhile, and if your drive home is a short one, the a/c system may never have time to fully compensate once the car's interior has cooled to match the interior's temperature. To make matters worse, if your drive home is one through the city, you can expect your a/c to suffer. The air conditioning system needs good, steady airflow over it's condenser (a radiator-type part located just behind the front grill) and lots of starts and stops in a city or heavy traffic area can obviously prevent this. Above all though, the most important thing to remember is that with even a perfectly functioning a/c system, you can usually only expect about a 30 degree drop on average from the outside air temperature. So, if it is 100 degrees out, depending on the ambient pressure and humidity (also things which can affect an a/c system's efficency) you may only get air that's 70 degrees out of your vents. I would recommend always rolling your windows down half an inch or so, and park in the shade whenever possible. Also, putting a sunshade in your front (and sometimes even rear) windows, and having your side windows tinted (when legal) can go a LONG way toward keeping your interior as cool as possible when sitting parked in the sun for long periods of time

Air conditioning gets hot when stopped , fine as long as driving


The refrigerant may be low, also could be that the a/c compressor is going out. Have it checked
