Car seems to be idling rough, when in park car RPM needle goes past 2 and then stays there, when car is put into drive RPM needle comes back down. Car accelerates without pushing gas petal, it has done that two times. When it first starts up in the morning it does do it, but as car warms up it starts acting up. Could this possible have something to do with the cruise control? I have not used the cruise control but is it possible that is froze up.
