Off Topic - Engine error code readers - need recommendation

[bbarn]

for the geeks (like me), I bought a bluetooth ODB reader that links to an Android phone/tablet using an app called Torque. You can also link them up to a laptop via Bluetooth as well.

This is the one I use, this particular model is not great on Fords, but for general use it is acceptable. It will let you read codes, see realtime data(engine/transmission, plot engine data on a map and reset codes once corrected.
