Driving down the freeway, running great, then all of a sudden,major loss of power and when I pulled to the shoulder, the engine idled very rough and would die at idle. I could restart the engine but it would idle very rough and die. The engine sounded very different when I turned the motor over to try to start the engine.
Yea sounds like a belt or Chane but dose not jump going down the road much most of the time will do it when u start the car..

I would suspect a vacuum leak. At idle under high vacuum the air fuel mix is being leaned out until you have misfiring so bad the engine quits. The exhaust smells rich because even a lean mixture, if it doesn't light off, if full of unburned fuel. At road speeds, the vacuum is low so the engine doesn't care if there is a small leak somewhere. It is getting most of its air through the open throttle. Check all your vacuum lines but remember that even if every line is okay, it could still be leaking from an old cracked intake manifold gasket.

I would suggest hat you replace the timing belt. The noise that you hear is the belt.

Hello
I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

try chem12 spray. Clean mas, then spray into intake manofold w/engine runnign at 2k rpm. Check for oil leak in spark plug recesses causes a miss that the computer picks up and tries to balance.Did this to my car. it works
