Question about 1998 Ford Contour

1 Answer

1998 Contour, When it is cold it runs fine. But when it warms up it idles very rough at low RPM. It dies sometimes when at a stop light or even going around corners. When it is acting up like this it smells very bad. I can park the car and wait an hour or so and it will run fine until it warms back up. I have also noticed my temp guage is not working now. I do not believe it is overheating as my fans are running correctly. Replaced the plugs, wires, timing belt, tensioner, pulleys, water pump. Within the last 300 miles. But it is still running rough after warm up.

I notice that you replaced the water pump,Did the car over heat at any time, If it did end you didn,t stop right away when it first happen, It can do real serious damage to the engine, That will give the syptons you are describeing,If you notice that the car starts to use more oil, That is a deffenet sign there was damage done to the engine,That it done damage to the piston rings, Have you changed the thermostat in it? It tell me allso when you stay your temp gauge is not working that the termostat .Might not be functioning(Properly)
End mess up the temp (Sending) unit. If the car is over heating there will be a loss in power,

SOURCE: 1997 Ford Contour with a rough idle while stopped

This is a common complaint on these cars. I own a 96 myself.
Assuming that you engine is fine and runs smoothly under normal operation, and just is rough "feeling" at idle while stopped; then I would suggest changing the motor mounts...the mounts may not be broken, but the rubber isolators get worn and soft, and transffer normal engine vibration into the chasis of the vehicle. Mine was doing the same after changing the mounts good as new again.
Please note...don't use cheap mounts, by the better grade/quality mounts.

That mechanic wasn't lying. I currently own three of them and I know a lot of people that own them and they all have a rough idle. The engines are internally balanced and they don't have dampeners, so you get the engine vibration transferred to the car and that is what you are feeling.

Idles roughly, then low when stopped or in park, then dies. Decreasing gas mileage. Slow to accelerate


Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

Ford Contour apparently starves for gas, dies.


tell your mechanic to replace the fuel filter. This part is usually less than $10. It should be replaced aout every 50K miles.
