Stumbling at high boost

The specification is 13 to 33 ohms at ambient.  It's the only soldered
joint on the car ex-factory, and the most troublesome - it probably
accounts for 80+% of all WR performance problems.  These days we don't
resolder it - we strip back and crimp two female car speaker connectors
to the harness lines, then cut off the spot-welded contacts from the
sensor using a pair of flush-cut wire cutters.  If you neaten up the
sensor contacts with a needle file, the speaker connectors (slightly
opened) just slide on.  The job is completed with some heat-shrink
over each connector.
