Hello all,
First off, thanks for a fantastic group of knowledgeable helpful folks.
So much to learn..

I am going to be buying a DSO for general electronics usage, but also automotive diagnosis.
Scope likely DS1054Z

Suggestions for probes, cables, sensors for the scope? Maybe home-brew..
I have a clamp on current probe..
Wondering what type of sensors/probes for auto diagnostics.. Secondary ignition, etc.

Also, place to purchase DS1054Z ?

Thanks so much!!

Here's a DIY example of a coil over plug sensor: http://www.ford-trucks.com/forums/1159255-poor-mans-cop-scope-probe.html
I know commercial ones are available, but might be fun to experiment with a roll your own..

The Pico First Look Sensor (Pressure transducer) is quite handy, albeit pricey. It is not a pressure sensor, it only measures changes in pressure, but this is useful for checking for low compression/leaky valves etc, without pulling spark plugs and carrying out a regular compression test. Attach it to a vacuum take-off on the intake manifold or stick it up the tail pipe, trigger off cylinder 1 and use the chart to line up the defective cylinder(s) to your trigger point.
A great place for automotive info is here:

I have no affiliation with either Picotech, or Autonerdz.

Regards.

Thanks for the link! I wasnt aware of that site.
I agree, Pico pressure transducer is fine piece.. But pricey for non-professional need.
I am finding youtube videos on DIY pressure transducers for scope usage.. Cool stuff.

Pressure pulse sensor would be another item to use.

Here is a link to a DIY unit: http://www.locostbuilders.co.uk/forum/47/viewthread.php?tid=200739

commercial version:
