Where it doesn't happen a lot , or consistently, i think I have ruled out a leak.
Possibly a sensor? Any ideas? Way to test ?
Thanks in advance, jeff

If you have confirm that the bag(s) are good then you may want to check the sensor for the height adjustment (not sure if the 2001 model has it).
Most of the issue on these things are the bags. Especially if you live up north with the winter weather and the salt. It eats into them over time.
