I have the following two issues, and I want to get them find a fix before they cause any related damages...
Driving at a constant/consistant speed, my car jerks as if I were tapping the throttle peddle and then coming off of it. This jerking of the car is subtle at lower constant speeds, and more noticeable during freeway speeds. So an example would be driving at 65mph and the car would slightly slow followed by a slight lurch forward as if the throttle were to be blipped. This does occurs when I use cruise control, but not when I am accelerating.
My car idles at 900rpm and dips slightly below 900rpm to shoot upwards of 1200-1400rpm and then momentarily back to 900rpm before it does it again. This would occur at idle every 5-15 seconds when I am pressing my clutch in. If i am in neutral and no clutch, the rpm's do not jump around as much.
Any help or insight would be greatly appreciated.
Thanks in advance!
