00 impala is getting bad gas mileage could it be thermostat or o2 sensors check engine does not light up?
are there any other symptoms? have you ever had a tune up done?(plugs, wires) oil,air,fuel filters been changed? check or do some of the above to see if this helps.

Yes. Your engine will get the best mileage at full operating temperature. If the thermostat is removed or not working properly causing the engine to become too hot or not hot enough it will affect the operating efficiency or your engine which will decrease your gas mileage. Read More
A bad thermostat can cause a decrease in gas mileage. If the thermostat is stuck open, the engine will tend to run cold. Not only will this result in a perpetually low temperature gauge reading and poorly performing heater. It will also cause the ECU to richen the mixture, since the engine will appear to be warming up to the ECU. This will result in poor gas mileage. Replacing the thermostat will allow the engine… Read More
Your engine will get the best mileage at full operating temperature. If the thermostat is removed or too low a temperature unit the engine will use more fuel. Read More
Not legally. If you do so, the engine will not run as well and will get lower mileage. Read More
Replace it with the exact same temperature thermostat as the one you removed. Do not run the engine without a thermostat. The thermostat is required to keep the engine running at the optimum temperature that will give the best performance and mileage. If it is overheating running it without a thermostat is not the solution. Read More
An open thermostat would keep the engine from heating up to normal operating temperature. The sensors effected can only report what they sense. The "check engine" light may throw a code like "P0116" (engine coolant temperature circuit range/performance problem). Read More
Yes the engine will run but not like it should. The thermostat is required on modern engines to get the engine to the proper operating temperature and keep it there. This will give you the very best mileage and performance. The optimum running temperature for most cars is 195 degrees Fahrenheit. without a thermostat the engine will take a long time to reach that temperature all the while wasting fuel. Without a thermostat the engine… Read More
If you mileage has dropped dramaticly in a short span of time there is one very probable answer. The thermostat to you engines cooling system may have puller through into the engine itself, or simply be in need of a replacement. With no thermostat the coolant is constantly circulating the engine. It is supposed to only do this at a higher temperature but if the engine is constantly cold it will be running a rich… Read More
An Accord will run without a thermostat. But, it will not operate properly. The heat, fuel/air mixture, even the mileage depend on the thermostat keeping the engine in the correct temperature range. Read More
Thermostat is on the left hand side of the engine block as you stand in front looking at engine. you should see a black rubber hose about 40mm wide, this goes on to the thermostat housing. the thermostat has to be replaced with complete housing and sensors. quite expensive as thermostats go. Read More
Yes, you most certainly do. If you have no thermostat installed then the engine will take a very long time to reach full operating temperature and may never get to the proper temperature. The thermostat allows the engine to warm up quickly which helps prevent engine wear, reduce engine deposits, and emissions. The thermostat keeps the engine at the proper operating temperature for the best performance and best mileage. Running a modern computer controlled engine… Read More
My temp gauge won't go past the beginning of the normal mark I have replaced sensors and thermostat.?
Your cooling fans may be coming on or you might have a low temp thermostat. Either way, a cool engine is better than a hot engine. Read More
your engine will never warm up properly. it will decrease gas mileage. engine will not run right. just get the right thermo, and replace it. Read More
check engine light on,getting poor gas mileage on 1996 Plymouth neon Read More
yes, otherwise the engine will run too cool and you will get horrible gas mileage Read More
Fuel consumption is determined by several factors: * The displacement of the engine. * The design of the engine. * The driving habits of the operator. * The condition of the engine, ie. whether all of the sensors, injectors, carburetor, valves, rings, sparkplugs, plug wires, other ignition components, etc., are functioning as designed.

Have a mechanic check the O2 sensors. If one is out then the computer will give the engine too much gas. I have also seen some sensors go completely out and the check engine light does not come on. Read More
Many of the engines sensors do not operate until the engine has reached running temperature (195 degrees F). Without the thermostat the engine won't reach that mark. It may also trigger the check engine light to illuminate. Read More
Would it hurt to just take your thermostat out because my car is getting how even though i have new water pump radiator hoses?
the car will run with no thermostat installed but performance will be affected. the thermostat not only opens when the engine gets to preset temp but also closes until the engine reaches normal operating range. when the engine is cold either the choke or the fuel injection system richens the fuel/air mix. smoking, fouled plugs,and reduced gas mileage might result.

To find the thermostat, first find the upper radiator hose going from the radiator to the engine. It's a big 3 inch hose. Where the hose connects to the engine is where the thermostat is at. It's called the water outlet housing. The housing contains the thermostat, 2 sensors and the hose going to the heater. Take this housing off and the thermostat is located inside of the housing. When replacing the thermostat make sure… Read More
Can? Yes, but should you? No. The thermostat is an integral part of the cooling & emissions system. The thermostat allows the engine to reach optimum operating temperature very quickly which is a good thing. Without a thermostat the engine will take much too long to reach this temperature and in fact it may never reach it's correct operating temperature. Engines run poorly when cold. Once the engine reaches its operating temperature (generally about 200… Read More
If the thermostat is stuck open, the radiator is able to cool the antifreeze faster than the engine can heat it. Read More
Yes , but it will be like having a thermostat that is stuck open It will take longer for your engine to warm up , the heat from your heater won't be as good , your gas mileage will be poorer , maybe your check engine light will come on , it will pollute more etc. Read More
There are two temp sensors on that year engine on for the gauge which is screwed into the head near the exhaust manifold and the other one is for the idiot light it is near the thermostat. Read More
Can a car go without a thermostat I just removed the thermostat from by Ford explorer car so I just need to know if there are any effects to the engine?
yes you can drive it without thermostat the only thing is before winter you will want to replace it or your heater will not work ( also the engine will take longer to warm up , the gas mileage will suffer , the check engine light will probably come on etc . ) Read More
Water is not getting to your car's engine It goes through the radiator but not to the engine What could the problem be?
The thermostat would be the first thing I would check. Read More
The thermostat doesn't open until 195 degrees. 210 is not that warm for that engine. Read More
There are two sensors/sending units. One (the sending unit) is located on the driver's side of the engine block (just below the exhaust pipe). The other is located next to the thermostat housing on top of the engine. Read More
If your engine thermostat sticks open it will run cooler on your temperature gauge and you won't see the temperature gauge go up to the point where your engine thermostat opens and then the temperature gauge will show a drop in temperature , your check engine light will probably come on , your gas mileage will be less , the heat from your heater probably won't get as hot If the engine thermostat were to… Read More
It will depend on which engine you have. The 2.0 DOHC has 2 sensors; one for the temp gauge and one for the ECM. The temp sensors are both located on the thermostat housing; one is on top and one is on the bottom of the housing. The Sensor on the bottom of the thermostat housing is for the temp guage. The other i believe may be for the fan but it does not match… Read More

Why is my 1998 Frontier getting terrible gas mileage in cold weather when it was getting good mileage in warm weather?
I suspect there are several possible causes, but I can only think of three right now. First, it could be a defect in the electronic COMPUTER. Also, the computer makes its fuel mixture decisions based on several pieces of information it receives from SENSORS, and if one or more sensors have become defective, the the computer could be providing an over rich fuel mixture during cold weather. The third possibility is that the THERMOSTAT is… Read More
yes Additional answer: You can, but shouldn't and don't need to. The thermostat is designed to keep the engine operating at a certain temperature. This temperature has been proven to make your engine run more efficiently, more power, better gas mileage, longer life, etc. If you live in a climate that has cold winters, this thermostat is part of what makes your heater work. If removing the thermostat in order to help the engine run… Read More
The check engine light came back on saying I needed a new catalytic converter. What will happen if I you don't replace it?
Your gas mileage will be greatly effected. You could damage the oxygen sensors as well as other sensors. edit: I don't know about damaging the oxygen sensors necessarily but the oxygen sensors do return information to the engine to change the fuel mixture of your car, resulting in poor fuel mileage. Also your car will create more toxic pollution. In an older car without an oxygen sensor this is not a problem. In fact, it… Read More
That year engine requires a 195 degree thermostat due to the computer system/sensors. It is NORMAL for that engine temperature to run between 195 to 210 degrees depending on the seasons and how you are using it. Read More
