Dies when comeing to stop iduling ruff


Is the check engine light on ? If so you should have the computer scanned for trouble codes first. The codes will point you in the direction to look for the problem.
You may have two different problems. Engine dies at a stop is usually a dirty throttle body or problem with the idle air control valve. Running rough could be a long list of things.

Car dies on freeway.Never overheated!!! What could it be.I'm guessing the fuel pump


Hopefully you don"t need gas first in the tank.While driving did your motor seem to ruff suddenly and as you went slower to a stop did you pull over and turn car off? When you turned it on again did it start up really ruff without giving gas.Can be that you need a fuel injector replaced you can not clean it because it also works electronic.Toyota runs better on higher octane period.

When running at a stop the idle gets really low like its going to die but it doesn't and here lately it runs really rough at any steady speed it feels like it hesitate the motor has 204,000 miles on it


do a compression test on the cylinders.If that checks out ok,change the spark plugs wires cap and rotor.The idle air valve on the throttle body could be working incorrect causing a low idle.clean the throttle body with a cleaner spray.

My 84 caprice classic it has a very shakie idle


When you start your car, you step on the gas and turn the key, you have set the high idle feature on the carb as part of the warmup sequence. When you step on the gas again, you kick high idle off ...if premature, the engine is cold and it runs ruff, and wikll likely stall under some circumstances until you have reached operating temp. The reason for the ruffness ...is gasoline becomes 'gas' better when the engine is at operating temp than when the engine is cold.

Your battery is getting tired. When you step on the gas and the lights get brighter, it is because you are running the alternator at a higher speed and you are making more electricity which the lights are more than happy to gobble up.

Keep in mind your car is notonly a Caprice Classic ... it is a classic, 26 year old vehicle. It needs a little more TLC than a newer model.

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
