Hitting bumps in the road changes the way mine
runs,too. At least it really seems that way. I've been
thinking about this a lot,and there's not a lot of
mechanical things that could be affected by bumps (it
would take severe jarring to affect mechanicals in a
transmission,I would think). But there are lots of
electrical connectors and even solder connections in
various modules that are definitely affected by
vibration. Wonder if you have a loose plug or
intermittent connections somewhere? I had a Dodge
Intrepid years ago that the remote quit working on.
Sometimes it would work,other times not. Found that
problem myself,it had broken solder connections inside
the remote receiver module! (I did need the service
manual to know where that module was,though.)
