Need help!! I have a 2000 expo w/ 127K with air ride, and for the past two weeks every time i come out to my truck in the morning the truck is completely sitting on the stoppers. It has never done this before, it stays pumped up im thinking that there is a leak, or the lines need to be replaced going into the bag. it will inflate fine after starting, and ride fine, but when i turn it off it will fully deflate in about 4 hours. This morning while coming into work my check engine light came on. I recently tuned it up about 3 weeks ago. If anyone has any info would be greatly appreciated.
