Crazy Speedo causes crazy accelerating
When my 01 Grand Sport is not running the speedo sits at 9 mph. When running and not moving, my speedo needle goes crazy, flipping back and forth. When doing this, if I try to pull out of my driveway (in D or R) I get jerking out of the van, which then smooths out when I get going.
I have changed the in/output speed sensors with no change in behavior...however it did get rid of all of the trans codes that were indicative of speed sensor issues.
It was not until I was experiencing the speedo issue and jerking of the van, that it constantly showed 9 mph over.
Any ideas on what is causing this or what I can do to fix it all?
