bouncing timing...

[RumpRanger98]

So I hooked up my new obd II scanner I got that also reads live data. I noticed when I first fired it up the timing was at 26* plus or minus 1. As it warmed up it dropped down to 17* and would bounce anywhere from 12* to22*. If I would rev it the timing would bounce to 26* and showed 30* a couple of times.

Is this normal? or is my cam synchro sensor going bad? 99 ranger 3.0 btw.

timing should adjust if you rev it up IIRC.
It does on distributor motors anyways, unless the dist. is locked.
