The victim is a 1991 Jeep Cherokee 4.0 with an intermittent stall, hesitation and no start. Naturally the Jeep would not act up in the bay once the scope was hooked up.
However, a short road test flushed out a single bump symptom.
He used a 3223 Pico two channel for the capture and used 5 seconds per screen streaming with 980,393 samples per channel. This means there were 5 microseconds between samples on each of 18 screens he captured. Never even filled the 32 screen memory.
He captured several pre and post symptom CKP failures on the short road test, including the actual failure that caused the symptom. I made this little exam movie so we could show how much information was actually captured in a very short time. No other automotive scope has these capabilities.

The circles and arrows with a paragraph on the back of each one explaining what each one was
is a part of the software used to make the movie, not PicoScope.
