What would you like to do?
no try running a thicker oil so that it doesnt loose viscosity so quick. 1991's are motor driven oil puimps so if the oil is to think to pump it will run rough

Answer possible vacume leak in the egr valve or bad valve itself.
Answer The rubber air tube going from the MAF to the throttle body may have a crack in it.
When a 96 jeep Cherokee gets a little hot about 230 will this make it start to run rough and want to die?
Love my 96 But runs hot I have a 96 Cher. sport 4.0 HO with about 130k miles on it I don't remember when my heating problem started but I have replaced: water pump, the…rmostat, fan clutch ( I was actually looking for a direct drive fan clutch replacement like gm makes no luck), flushed the system, replaced electric fan, and cat converter ( if its simi clogged it could cause the engine to run warm. I guess about the only thing I have not replaced or tryed is the actual temp sensor and guage to see if its lying but the engine really does seem to be hot as well as smell hot0 Someone said to remove the thermostat, but these engines are designed to run at around 195deg so that might mess up the computer. If anyone has any answers I would appreceiate the help also!
How do you replace the water pump on a 91 ford probe Car overheats but has new radiator and hoses and new thermostat gets hot and runs out of water but i can find no leaks any suggestions?
Answer Engine overheats When …a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.

What could be the problem in a 1993 corsica that runs hot after you have changed the thermostat - is fine in the morning but as the day gets hot it runs hot and steams?
Answer Corsica overheating problem You may have not enough coolant or the wrong kind of coolant. You may have used a winter thermostat rather than a summer thermo…stat. The radiator cap may not be the right one or isn't functioning properly. The pressure escape line off the radiator may be obstructed. Your radiator may have a number of fins clogged, or the coolant pump may not be operating properly. The fan belt powering the pump may be loose or slipping. There are multiple possibilities!
Why does my 91 Dodge shadow runs smooth when it is cold when it gets warm it starts to run rough and not smooth?
Maybe a faulty coolant temperature sensor. The air-fuel mixture is rich when cold, which is OK, but as the engine warms up, your mixture is too rich. Is your fuel economy suff…ering, too?
Your 1991 Cougar might be running rough because it needs to be serviced. Try changing the spark plugs, spark plug wires, and checking for water in the fuel tank. You might… also have an issue with fuel injectors that are clogged.
My 1993 Ford Taurus idles rough when I start it. Then it stalls when it gets hot and it will not turn over until it cools. Does anyone have an idea why Thanks?
The possible problem could be a faulty idea air control valve or a dirty throttle plate. Also, inspect the car for any vacuum leaks.
On 91 Geo Metro Convertible .Why do you have to run a hot wire to the coil to get it to run.I have replaced the ECU and that did not work?
Does it have an ignition control module? That may be the cause. Or possibly a MAP sensor or a Crank position sensor or Cam position sensor. Check those first.
A runtime error means there is a problem with the application you are running. Here is an explanation for runtime error 091 . 09 means its a program error, verify that t…he program has all of the latest updates. If already updated try reinstalling program. If you continue to have errors then it's time to contact the people who sold you the software...it's a computer program error in the application. go to asknerd.net and type in runtime errors there is a list of all the numeric codes and what they mean.
It depends but probably yes. ---- It may be due to a vapor lock. This occurs when gasoline, either in the fuel line or in the carburetor turns into vapor. The vapor …arriving in the cylinder is too lean to burn. Try protecting the fuel lines and carburetor from engine heat.
probably a head gasket
when you oil gets hot it tends to thin out. Say your using 5w-30 and when the engine gets warm it knocks it means either the oil is to thin or oil is not getting to that compo…nent. next oil chenge try using the lucas oil stablizer and see what it does. It should solve the problem but remember lucas oil oil stablizer takes the place of one quart of oil.
This is a common problem for Cherokee's there is not enough ventilation for the engine, I had a friend buy aftermarket hood vents and cut them into the hood, The engine heat c…auses the fuel bar to vapor lock and slowing or stopping the flow of fuel to the engine. I am not a mechanic, this is just from past experience.
Because it's sitting in the sun.
It is a safety feature for the engine I believe so the engine is not damaged.
