Can bus signal

Can anyone tell me if this can signal is normal?  

It would be better if you could post an actual screenshot, instead of taking a picture of the screen with your phone, so that we can see the voltage, time, and sampling values. The .psdata file would be even better.

However, with the poor image quality considered, that looks like a normal waveform, to me.
 

Yea sorry about the pic it didn't look that bad when I took it. My main concern was with the math channel it sometimes showed a .3mv difference between the 2 channels. I'm new to scopes but what ive seen is that it should stay at 0?    Thank you for the reply..hope this pic shows up better 

Got to work on the car an get some better images while it was running.  The reason im even looking at this is because the car stalled while driving, No codes, hasnt stalled since and drives fine. only thing ive seen so far is on my scan tool while graphing the tps app o2 sensors every once in awhile the voltage will drop/spike to 0.  Doesnt affect the car at all.  Any help is much appreciated.
