Many times the connection to the wheel speed sensor may be loose or corroded, or it may be the sensor itself. Replies to this message: alphahammer (Jun 14, 2009 11:31 am)
#17 of 18 2002 Montana Missing by alphahammer Jun 14, 2009 (11:30 am)
My 2002 Montana has an issue with randomly jerking as I drive. It happens at varying speeds from 10 mph up to over 70 mph. I will be driving and suddenly the car will give a little jerk or 2. The jerks are harder and more noticeable the faster that I am driving. I thought that somethimg is causing it to miss but the shop told me that they can find nothing with the scope and that it my be the 'throttle positionin sensor'. Any thoughts

Replying to: ray80 (Jun 03, 2009 3:18 am) It was the sensor connection. It was not easy convincing them to check it out. They put in a new wheel bearing under warranty forlast one done first.
