Hello everyone. I just bought a 97 Cobra, Black on black with 69000 miles. I've had it on the road for one day and the idle is a little loopy. What could this possibly be caused by? Thanks

when the car is idling, what rpm does the rpm gauge read? Or is the rpm needle slightly bouncing up and down every few seconds? You should be idling at about 900rpm. If you are way below that---then you need to adjust your idle speed. This only applies if you have the symptoms that I just mentioned.
