The van drives completely fine, however at random times (while driving and at rest) the idle will jump to around 5000rpm. After a few moments it will come back down to normal idle rpm. This is completely random and doesn't happen everyday. I have checked the cable adjustments and the cable seems fine. Is there a sensor or a setting that would cause this problem?
