Why does your '91 S-10 run rough after it gets hot?
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
Was this answer useful?
Thanks for the feedback!
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.
Sounds like an electrical short or a battery failiure, which can mean a new battery ,a new phone, or that somthing is shorting the length of the circuit . remove the bat…tery immediately since they can explode in rare instances. First try another battery, if the problem is still there then its either a phone short circuit or an obstruction short circuit which would either require cleaning or rewiring. Hope this help :)
Why does temp gauge on 2000 ford Excursion suddenly jump past hot causing engine to run rough and lose power when engine is not really hot?
If you are 100% certain the engine is not hot, but it shows hot and powers down, it may be as simple as a bad temperature sending unit. A lot of vehicles are equipped with a "…safety" mode....when the temp gauge registers hot, it'll cut the power down to help avoid damage to the engine. This would be a good place to start.
Backfiring in a nutshell: A backfire is when the ignition of fuel doesn't take place in the ignition/combustion chamber, it(a backfire) can take place in the intake… or exhaust. It can be caused by a fuel to air ratio not being correct, also if the timing of the spark is not just right that could cause it to back fire. It could be running lean with not enough fuel and too much air, or could have too much fuel and not enough air. It could be because the intake valves are not shut when the combustion takes place, therefore the combustion would take place in the wrong spot. The most likely cause are from: 1. Incorrect timing, the timing issue could be caused by bad wiring/ or bad ignition. 2. Incorrect fuel to air ratio, bad fuel filter, low fuel pressure-caused by weak fuel pump. Most cars will have the same cause for backfiring, as long as it's an internal combustion engine it shouldn't differ...
%DETAILS% I had the same problem in my 99 firebird....check the engine module or it could be the coils mine was both along with a faulty catalytic converter..if you smell a ro…tten egg then its the cat... goodluck Check the current at the fuel pump; fuel pump might be going. TRY THE O2 SENSORS HAPPIN TO MY 1996 IMPALA TO BUT THE WIRES WERE CROSSED ON MINE
Answer possible vacume leak in the egr valve or bad valve itself.
Sometimes an ignition coils will break down under heat and not fire properly. Start there and see if it helps. Billy
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?
My hooves are striped but my body is not I can run a great distance without getting hot. What breed am I?
A Ford Explorer that runs rough may be experiencing a clogged fuel filter, dirty air filter, or worn spark plugs. A proper tune-up can solve most problems associated with …an engine running rough.
ECM on these have a habit of going out. They were dipped in plastic to protect them but over time due to hot/cold expansion cycles the plastic pulls the component off th…e boards. There was a move to get a recall going, but it was unsuccessful. They are very expensive, but you can get one from a junk yard for about $25-45 these days.
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.
If not electrical issue what about a vapor lock created by carb problem? Swear it was cheaper to pitch. Since it had a non-adjustable carb at possibly $40.00 bucks to experime…nt. Theory applied though. When cooled down with water it would start but not run long. Even replaced coil and then stupidly never properly tested electric. Grab that coil wire and spin it. Can you dance without a partner? Got another engine from a similar model that the deck was messed up on. Swapped it out. Robbed old engine of new parts and other usable items and recycled the steel. Taa Dah?????? Maybe for you too??????
If you have a code reader, you can retrieve the codes. It's possible that the MAP (Manifold Absolute Pressure) sensor could be faulty, thereby sending no signal/wrong si…gnal to the computer. Most repair shops will charge about $100.00 to diagnose (hook up to their computer for code retrieval), then deduct this charge for repair of the problem. Some codes are "hard", meaning that they will cause the Check Engine light to come on. Other codes are "soft", meaning that they will not cause the Check Engine light to come on, but the problem still exists. Make sure you clear all codes if you retrieve them yourself. If you don't know how to do this properly, just disconnect the cables from the battery and wait for about 1/2 hour, then re-connect. Another idea may be to have the timing checked. I just changed my MAP sensor after retrieving the code with my reader. The MAP sensor cost me about $79.00 at NAPA Auto Parts, and about an hour total time (diagnose and repair). Hope this wasn't too thorough.
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.
What are some possible cause for a Lincoln mark viii when it runs rough when its cold but then smooths out when it gets hot?
Could be a crack in one of the power pack tops , spark plug wire or wires. Just a couple of things that you didn't check
well, there's a doohicky called a TCC solenoid. Basically, when the engine exceeds a certain temperature and the vehicle attains a certain speed, this solenoid engages and loc…ks the lower gears out of the transmission. This feature significantly improves mileage because it makes the transmission lighter. When the vehicle drops back below a certain speed, the solenoid clicks off and drops the lower gears back into the drivetrain. However, this particular solenoid is located IN the transmission, so it gets sticky after a few years, leading to a situation where the lower gears stay locked and the car makes an unpleasant BAM sound as it tries to shift into lower gears. The short term solution is to disconnect the solenoid, though this will cost you a little mpg. Any mechanic worth a cent will be able to do this in about 30 seconds and won't charge you for it. Replacement is rather expensive as it involves taking the transmission apart.
