Question: What could it be??
When the car is started it idles very rough and the RPMs fluctuate, whether it is warm or cold. When driving it chuggs and the RPMs fluctuate when holding the accelorator in the same position no matter the speed or the temperature. It seems to be worse after being stopped and trying to move. When you turn the car off the (we think it is the) idler control valve that has a part which moves against the accelorator cable and makes the pedal clunk and moves up and down for a while then stops on its own. About the time all of the problems started the cruise control stopped working also. Could this be the whole problem or could there be more to it. Any Ideas on what to check out or change would be great.
