What's with the spin at about .5 on those runs. Looks like it dead hooks the tire and drives into a spin. When my car does that I am slow too. And there is a difference in trans pressure that shows up on the RPM too from what I see.

The car does that every time. It is the bias ply "getting up on the tire". They wrinkle up (first spike) and then spin about 3/4 of the turn (second hump). If you are not monitoring driveshaft or have a good video you would never catch it. Also there are two curves there overlayed if you look close. The problem does not effect the driveshaft which means the trans is not the problem. The chassis is doing the same thing - its a power issue. Hence the reason the rpms differ.

Another clue I found last night when again going thru the grid. I have an alert for a low crank sensor. But grid does not show when or how many times. I am rarely in the grid so if could be 6months old.

Right now I have a new crank sensor, and cable. Also ordered a new coil but not putting that in unless it is still acting up.
