Tested it with Torque Lite, connected and worked just fine. Upgraded to the $4.95 app tonight. Was able to watch my vacuum and timing, was mainly curious - not really looking to fix anything. But noticed that coming off a higher rpm back to idle, the vacuum dip lower before settling out, and I also noticed the timing advance pretty bouncy at idle. Anyone look at that those parameters before under those conditions? I have noticed a little roughness at idle, so these results match up... not sure what would cause that though.
Thanks, luv that, captured it and saved it ...I acquired my vac gauge when I was 16... was a gift from a senior citizen neighbor that had been into racing boats and engines. I said thanks ( thinking, what the heck am I gonna do with that?). Took years before I ever actually plugged it into anything. Still have that gauge, and used it just this year to figure out what was going on with the truck's 4x4 axle actuator. Also nice to have is a vac pump, to simulate conditions.
So it sounds like that the vac might be just an artifact of the timing bouncing around. So need to just focus on the timing bouncing a little at idle.... hmmmm....

My first place to look for that would be a stretched timing chain.
