I don't think I am seeing any anomoly here. What I am seeing are fluctuations caused by the conversion of analog voltages to digital values. Your graphs are simply zoomed in way too far.
Let's take the throttle position for example. It looks to be spiking up and down. However, on close inspection these spikes are roughly just 0.4%. Not enough variance to cause much of anything.
The throttle position has a range of 0% to 100%. A single byte has a range of 0 to 255. So to represent the throttle position with a single byte each bit is 100/255 = 0.392%.
So that "spike" in the throttle graph is the minimum value a change can be, one single bit.
Similar for the MAP sensor. The MAP sensor value is reported by the PCM in kPa. To convert to psi it is multiplied by 0.145038. So the minimum change in psi is 0.145.
The graphs will look like they are jumping about when zoomed in too far.
I think what I am seeing in the first set of graphs may be this...
The engine idle RPM drifts higher in response to something like an intake manifold leak. The PCM sees the idle speed going higher than the desired idle speed and tries closing the throttle a very small amount. This causes the throttle position displayed in the graph to fluctuate as the digitized value approaches a rounding point in the equations as the throttle position just barely reduces. The closing throttle lowers the MAP value and a similar artifact of the equation for the MAP sensor causes the drop seen in that graph.
I think I might look for a intake manifold leak or mybe a leaking EVAP purge valve or the like? Just a thought.
